I'm not Microsoft, but as a user I'm worried. I certainly will not be supporting these kinds of anti-user lock-in SaaS platforms. I'm hoping users will ignore them, and they will fail.
I hope so, but I doubt this will happen, thanks to business users.
When you run a company, you don't want your graphics stuff to tinker around software and talk about freedom or whatever. You want them to get their job done, to make one graphic after another, to fulfil contracts. You need to pay for the software anyway, and as long as you have cashflow you can pay for the "services" (if you can't, you have bigger problems).
So, like always, companies will trade off freedom for convenience. The rest will have to follow, and the world will be worse off.
