I like to think of the freemium model as two different products. The first one, free, must be enough to attend the user's needs. And, without forcing anything, you use the free environment to showcase your second product, which is the paid one, that have different features (not just better ones).

When you frame like this you have both happy paid and happy free users. I imagine it like doing tourism on a city. You may just walk, doing your own sightseeing, with the free city's touristic brochure in your hands. Or you can look for a paid, professional, touristic sightseeing bus. Tourists don't see it as coercive, or even upselling. They are two different products that you choose between.

Yes I agree with all your points. But features aside, sometimes I think it's great if not only do you give extra utility with your premium features but users like to pay because they want to support you.
