for me the point about being locked into an ecosystem is reason enough.

Some more on that:

• Apple has actively resisted efforts by the EU to standardize
• iPhone doesn't allow you to install apps they haven't approved.
• Apple devices often refuse to interface with non-apple devices despite being physically capable.
• You cannot easily install other OSes on Apple hardware.
• Apple software is almost entirely closed source, and they likely have backdoors everywhere.
