Yes, but they also have a huge monopoly on communities that are hard to build up again on new platforms. Especially problematic is that many use it as forums, but all the information is not indexed on search engines, so you have no choice but to have an account and join a community to see what info is available. These communities are going to be held hostage and subjected to tons of anti-features going forward so the capitalists can get return on their investments.

I am not saying every business will give a positive ROI, I am saying many shitty things will be done to assure it. Even if ROI is positive, shitty choices will be made in an attempt to make it higher. That is a result of capitalism.
