I personally don't agree with a lot of what FB does, but I still find their products very enjoyable and useful. Contrary to popular opinion here, it hasn't made me unhappier to use FB or Instagram. I've only ever used FB for close friends and I still engage with them regularly on the platform. Furthermore, Messenger has been great for maintaining contact with my closest friend groups throughout the years. I also really enjoy browsing Instagram as a photography and I've made some really awesome and genuine friendships with other people in the community through it.
I'm not trying to excuse FB's actions as a company, but I'm interested if other people on HN also have similar experiences. I can honestly say that my life would be undoubtedly worse if services like Messenger did not exist in it and that it would be much more difficult to maintain some of my most important relationships otherwise.
