I feel like I am way too small and everything is way too against me to make this decision.
Now, someone in the head of a large company can decide to choose tech to use. Usually they fuck it up, like say destroying a corporate network with citrix, but theoretically they have the resources to choose.
The internet is like hostile and private individuals dont have luxury. Its a security issue. Want ad's that can have been compromised to download malware? tracking ? I don't think you have the luxury . Not with a browser anyway. You can pick a washing machine, similar cars, food brands with little personal consequence, but it does not seem a browser is one of those things to me. I think there are very clear smart and not smart decisions in that region, based purely on functionality.
Maybe in a deep future where its all safe.. right now there is like a possibility of getting your computer sacked because of a download (and possibly losing more then your data). It has to do with picking software that has the maximum probability of your personal rights not being violated. I think it surpasses any kind of political or other goals. It seems that there is a very disproportionate gap between your personal needs involving computers and far away political ideals. So I think you should take what you can get and be happy with it.
The only reasonable political statement that is sane to make is to make your own team to make a competitor product with your own team.. ideals. But not boycotting.
I think its just one of those things that on a local level is going to go against ideology. I have seen like THE MOST COMMUNIST ass practices ever engaged in like super duper conservative companies, because its the only practical solution at the time....

v. If they tried to use their "upper ideology" to solve those local problems, it would get smashed because it seems insane.
Its state level foreign threats that you might have to contend with on a computer. And trying to make it safe for whatever your personal desire is, would wreck the economy... so make due
