Trade Only?: Yes, you go first!
I don't know all the details but seems to me that if you want to make a stand, cut your ties. Don't wait a day to then do your goofy card reveal and continue to benefit from promotion provided by a company that you're making a stand against.
Doesn't seem like taking a stand to me. Seems like virtue signalling. Release a video explaining that because of these things, you do not wish to be associated with the company anymore, will not be streaming their games until at least some verdict has been reached and will not promote their products. I'd have full respect and support for that.
Putting a reveal off by a day just seems like you want to look to be making a stand but not actually have it get in the way of the privelages that you are receiving as a content creator. The accusations sound pretty bad, not a company I'd like to work with/for. But sure, put it off for a day, get a pat on the back for the great work you're doing to fight for fair treatment and then jump back on, make a goofy video and celebrate the same company a day later.
Seems to stink of hypocrisy to me..."oh no, no, Blizzard, you misunderstand me, I still want to do my card reveal and get the hits from the views etc, I'm just going to push it back a bit because you're awful, terrible people and I need everyone to know that I don't support all the awful things you do. I do however support your continued support in my channel please thank you very much kindlyyyyy"
100% the truth right here folks.
