If i thought my boycott would have any effect ...
Respectfully, that's where you're going about it wrong imho. You boycott because you personally don't want to support something.
It has about as much impact as voting in a representative democracy.
If you want to actually affect anything anything bigger than yourself you've got to actually become a nuisance. Direct action, campaigns, etc...
Buy anyway! (Haha sorry) The other commenter wasn't even talking boycotting, just thinking about if you really want to buy something. It's not a bad idea to think carefully before buying anything.
Do what feels right for you, though. It's just a game. Just as OS. One is a toy, the other's a tool.
