Honestly, Steam lacks a lot of pro-user rights. Developers are restricted by a lot of things that even itch allows you to do. Like a pay-what-you-want model or mentioning another storefront in your own demo/game. Not to mention that all you are truly buying on Steam is a lease to a copy of the game rather than the actual rights of owning a product. This sidesteps a lot of consumer laws in the USA.
