There has been a move toward centralization in the NFT space with Opensea and Magiceden marketplaces completely dominating the space, largely to the detriment of projects and / or users. One recent example: project royalties are now optional, so projects relying on these royalties from sales have had the rug pulled out from under them.

I expect we'll start to see some backlash where major new NFT projects build more safeguards into their contracts to try and reel back in some of the control the marketplaces have gained.
