You completely missed the point of my comment. "Objectively better" means that it's better in all accounts, as otherwise someone with different priorities could perceive it as worse, making it therefore only subjectively better.

And UWP is not better in all accounts. It grants Microsoft more control over the ecosystem, which is seen as negative by pretty much anyone who isn't Microsoft. Therefore someone who doesn't care so much about the advantages that you listed could perceive it as worse.

So, UWP is not objectively better, it's only subjectively better, which is why yes, people can very much justifiably complain about it.
