No, that's completely meaningless as a working definition, and also just broadly false.

Monopolistic companies often rank high in public polls of 'most hated / least trusted' companies.

Monopolies are more accurately described as using and abusing trust, by building up a reputation, and then betraying that trusted reputation once they've grown to become actual monopolies.

Enshittification can basically be described as the latter half of that process.

Its a slow motion bait and switch.
