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.
Well, stop expressing that people shouldn’t have to make choices about what they use, and maybe I’d give a shit what you say or do.
