Yeah, developers do need to eat, but this (IMO) snarky comment is hardly relevant to the OP.
1. Google is tracking you. They track you because they need this data to target better ads, this is how they make money.
2. The OP for this comment, says they use FOSS apps to get around Google’s tracking.
My comment is about - if you are against the idea of being tracked from profit, it would be a good idea to vote with your wallet to help open source developers get paid and to show that there is a viable business model for other individual developers.
