It's also weird how they call it "Sideloading" rather than just... installing apps. This is how modern operating systems should work, it's baffling that they bend the rules to make room for the exception.

That being said, I do think it's fine for them to charge for their software experience here. What they're really asking you to pay for is the development of the Pantheon UI, and the desktop/OS portion of it. There's not really any reason to pay that back to the Linux kernel besides good will.
