From a philosophical or practical standpoint? For me personally, I don’t care at all, i have no philosophical objections to companies running their own, closed chat apps. There are no hurdles for new entrants. And practically speaking, it’s a very small inconvenience to have to switch app when chatting to some friends. It even has some benefits, each of the apps will have fewer conversations to keep track of.
