I'm becoming more and more critical of these gigantic platforms. Perhaps we (for a random definition of "we") should have legislation requiring these companies to provide warranty for the services they provide, under a common set of minimal and inalienable rights, when the service is "free" but the company has revenue from ads and such. Having warranty for the services require some level of tech support, of course. Will this scale for a Google-sized company? Probably not, but that's their problem. It would even be better, for us as a society, if this makes these companies unsustainable; I can only dream of they being replaced by thousands of smaller ones for which the approach is sustainable.
