I still am not a fan of Stallman and still have to agree. Stallman sadly is right about most of the things he says. He has rather extremist stances sometimes, but that doesn't mean he is wrong.
Maybe I'll stop using some of those services. I actually have a resolution going on about not buying books off Amazon anymore. I just came across too many authors and bookshop saying that Amazon has the practice of saying "either give us specical/exclusive rights or we won't sell your book". I used to like Amazon, and heck, I also was understanding about them trying to avoid taxes, because most companies start doing that at some point, but extorting authors of books is way too horrible.
Also here there are counter examples. There is many games you can get from the developers, from Steam and from GoG for example, so why can't Amazon not be horrible?
Sorry, got a bit distracted about the Amazon link also being up there.
Calls for boycotting companies somehow aren't as popular anymore, despite having the internet and topics like the NDAP going viral. I think most people agree that in our society money has a lot of power and phrases like "vote with your money" have a point. Yet looking at the 60s till 80s those things were way more popular, which is a bit odd.
Be it Skype, Uber or Amazon. You don't have to hate them, but calling out bad practices and acting upon that information with not using their services seems to be a reasonable way to have a positive impact.
In other words it seems odd that certain minor design improvements can justify paying a lot more for a product or service, while that barely seems to be true for the ethics of a product - outside of the food sector that is.
