Mindfactory is selling Factory Recertified Seagate Exos and Ironwolf Pro.
They were also reportedly one of the shops (unknowingly) selling used HDDs with SMART values reset as new.

A project ending as abandonware is always a possibility. One reason projects get abandoned is losing funding, which can be secured by using dual licensing and selling some features to businesses.
They use AGPL so even if they broke their promise and restricted features, it could still be developed further (even if no new features got added). NGINX also uses a dual license.
It’s sad to hear about his passing. His videos about the Pi3 were great for me at the time. It’s been about 8 years and looking at the thumbnails of his videos brings back memories.
Given it seems to be a single guy doing his thing I don’t expect them to get bought out.
It’s a great service and incredibly cheap. With advanced pricing I’m only paying ~0,40€ per month. My domain + purelymail is less than I’d pay for other providers email only.
Edit: If Amazon increases their prices they’ll have to pass it on, but those should be pretty consistent. If you use your own domain (or an alias service) switching email providers is simple anyway.
