You are absolutely right - you can't just handover a kill switch for your business to a megacorp. However, there are a lot of instances where alternatives are not viable because of the same megacorps. For example, email is a major online ID and being locked out of it can be disastrous even for an individual. Ideally, you would want an email server of your own - but then the 2 major email providers simply junk the mail from small servers even when they have good spam filter score. Similar story about search engines directing traffic to imposters. There are no reasons to believe that this is unintentional. This wouldn't be a problem if everyone else had the same priorities as you. What alternative do we have other than to loudly shame them where it matters and get as many people to off those platforms?
