Yep. I believe it was for the release of 4, and if I remember right they just put the CD ISOs up for download with no copy protection and left any further patching up to the user.

Nope. Just Command & Conquer, Red Alert, and Tiberian Sun plus all of their respective expansions.

Not sure how a second remastered collection would be “scummy”, as RightHandOfIkaros puts it. The Remastered Collection was well done.
