Twitter, Facebook and Google can all burn for all I care. Never used Twitter until I got into Crypto and stopped using Facebook long before. I am trying to disentangle myself from google but it is hard. I do not use their search anymore and I use another provider for some emails. Decentralization is a threat to their respective platforms.
I agree with you about FB and Google, but I've found that Twitter actually has some decent ads before.
With that being said though, I would love to see less scammy ICO ads, so I think this might be a good thing in the long term.
