I think a lot of people will have a bad day. Some will swear off PC gaming altogether and switch to console, others might look towards Linux thanks to a friend or a helpful individual online, and a small minority will understand the problem and actively avoid the companies that caused the problem.
It probably won't affect sales of the company involved too much sadly unless everyone point their fingers at the company in the news.
Thanks! If it gets annoying I'll give it a shot.
