I know I have never boycotted a game from any of these companies and don't intend to. I play what games interest me, and don't play what doesn't interest me. If I let shitty business decisions and unhealthy developer crunch stop me from buying games, I basically couldn't buy any games at all, because just about every publisher and developer is guilty of this stuff. I can't think of a single game publisher who hasn't done something controversial at some point. Obviously some are worse than others, but I still play there games if they interest me.
Considering your playing habits I would say it is very unlikely that you buy games from companies that have the shittiest practices because that usually shows up on the product as well. Unhappy employees do to poor working condition, paying or abusive overtime is more likely to be bad quality.
