Freevee is just merging into Prime Video. All of the content will carry over (unless it outright expires by then). A lot of 'Freevee' titles are already available as 'Free With Ads' through the Prime Video app - and honestly, 'freevee' as a brand never caught on anyway so merging the content into Prime and basically serving as a perpetual 'free preview' of Prime Video' works on a lot of levels.
