The counterpoint to this is something like Craigslist which has not changed much since its inception and I think is perfect for what it is, but has been overtaken by Facebook marketplace.
My understanding is that Craigslist is still making a tidy profit, and it's owners do well. Sure, they might not need to testify in front of congress or buy all their neighbors land so they can have privacy, but most people consider that a plus.
