Hi everyone!
This thread is dedicated to Summer Loot Boxes and feedback about new system of obtaining event items with restrictions (time limit, no credits allowed). Original topic was only about "no credit allowed"  rule, but now it has grown up to something more complicated, with discussions about RNG systems in general, Blizzard politics in this field and other related topics. Don't be confused about the title, it's just a recognizable name =).
The purpose of the thread - give a feedback to Blizzard, collect opinions from mass media and other sites, propose better solutions and examples of loot systems, keep it all in one place to convenience and order. Feel free to express your opinions and copy paste interesting materials about the subject. Pls do not insult other participants of discussion (even if they have different point of view), be civilized and have fun!
Pls vote on strawpoll http://www.strawpoll.me/10918616

[b]History[/b]
[ul][li]August 2 - Blizzard released Summer Games Event, with over 100 new cosmetic items.
[i]"Though they can't be purchased with credits, each seasonal Loot Box you receive is guaranteed to contain at least one item from our Summer Games 2016 collection. While any Summer Games item you unlock will be yours forever, the collection will be heading back into the vault on August 22 when the event concludes."[/i]
https://playoverwatch.com/en-us/blog/20216482[/li][li]August 2 - People expressed their negative feedback about Summer Loot Boxes.
http://us.battle.net/forums/en/overwatch/topic/20747905428[/li][li]August 3 - Jeff Kaplan wrote an answer to complaints. Key points was:
[i]But sometimes we want things to feel rare and special.[/i]
[i]We wanted to try something new with this event. As we mentioned in the Developer Update, we're learning and experimenting with this event.[/i]
[i]we're seeing what works and what doesn't.[/i]
[i]We'd like to give the event more time and see how people feel as it wraps up. Maybe people will be feeling differently at the end of the vent. Maybe not.[/i]
[i]But I think letting the event play out for a few weeks is the right decision here. [/i]
http://us.battle.net/forums/en/overwatch/topic/20747905428?page=7#post-134[/li][li]August 4 - Original author of this topic pointed to phrase on Overwatch Advertising Page, where Blizzard promised, that credits can be used [i]to acquire any specific cosmetics you want[/i].

Also, Summer Games loot boxes' receipt stated the same
http://m.imgur.com/a/J4MiI[/li][li]August 13 - Blizzard silently changed the loot description on the OW page. Now it states [i]credits you can use to acquire many customization options[/i]
http://imgur.com/a/ZTNSd[/li][li]August 18 - Jeff Kaplan confirmed, that new non-event skins will be obtainable with credits.
[i]There are two versions of the skin:
A "pristine" version and an "overgrown" version
Both are available in the Hero Gallery for 1000 credits or can be obtained via loot boxes.[/i]
http://us.battle.net/forums/en/overwatch/topic/20748476172#post-12[/li][li]August 19 - Blizzard mentioned Summer Event in interview to PCGamesN. However, still no direct mention of the Summer Lootbox problem.
[i]We recently released Summer Games, it was our first event. It’s still live, people can go and play it if they haven’t tried it. We kind of wanted to see what players’ reaction to it would be. It’s our first one, we didn’t know what the reception was going to be like, and since we have, it feels like it’s been incredibly well received, there’s been a lot of enthusiasm over it, so right now we’re actively building and designing new events. So they’ll be coming. They’ll be coming in the near future, I can’t say what they are, but I think that there’s a lot of space inside of Overwatch for these events, and even new game modes and new brawls, like what we have with Lucioball. And I think it’ll be cool to tie some of them to real world events, some of them maybe to seasonal themes, and maybe there’s even fictional things inside the Overwatch world itself that we can tie an event to. [/i]
http://www.pcgamesn.com/overwatch/overwatch-world-cup-why-season-two-new-designs[/li][li]August 23 - Josh Engen (Community Manager) posted a announcement about ending of Summer Games. No clear answer about the problem.
[i]We hope you’ve enjoyed the Summer Games, and we're looking forward to the future of seasonal events like this. Thank you for all of the feedback you’ve provided us, and we hope to keep improving season after season.[/i]
http://us.battle.net/forums/en/overwatch/topic/20748496967[/li][li]Now - We are waiting for a CLEAR response from Jeff Kaplan about Summer Event. We believe he will tell, how event was accepted in general, what he thinks about Summer Loot Boxes problem, and what changes we might expect in the future. Current situation pretty much described in the post that summarizing grievances against Blizzard because of how their PR department has handled the situation (thanks HungryKarn):
