This isn't a strawman because the issue is about being angry over foul play, which there's some very strong points going in that favour, not many ones that say to the contrary. Here's the thing about your example, when was the last time you walked into a best buy and saw linux running on a computer for sale (not counting android or chromeOS). For that matter when was the last time you walked into any major electronics or computer store and saw that? Am I right in my guess that you say maybe a few during the height of netbooks and at no other time? So given that and given most people don't care enough to install or even investigate alternative OSes (Hell they don't even know what they're running they think their office version is their OS) how much effect do you think that really had? Marginal if any right? so going by your own rules isn't it childish to be angry at them over that?
Foul play is foul play and people have a right and even a duty to be angry over it, no matter if it effects a few people or a bunch it's still foul play. Not to try to invoke Godwin's law here but there's a poem that's relevant to this whole idea of "it doesn't effect me so why should I or anyone else care? It's childish to get angry over it":
