They’re websites. You’re arguing that people shouldn’t use different websites. On the Internet. Which is kind of how the Internet’s been going the last 15 years, and has turned out to be a total disaster.

The idea that the largest game in town should adopt the features of smaller players, rather than users exploring other options because there’s a slight inconvenience to the user just seems, I don’t know, incredibly entitled. It’s also how smaller projects stay invisible and die, leading to a monoculture.

So no, you’re not arguing that “we should have a monoculture!”, you’re just saying “people shouldn’t have to make choices!” which… leads to monoculture. And overwhelmingly supports the status quo.
