Yes, for quite a while these were actually naming their stuff Tangerine Dream and pocketing the royalties, even though many of the tracks were just old tracks with a couple of synth bits added. The band have had their stuff removed on copyright grounds and they keep popping back up with new accounts. Seems pretty shitty to me.
Plus, frankly, the recent TD releases are way better than this for me. All the original material from the Quantum Years releases has been solid, their best run of material since the Virgin Years.
There are so many TD-alikes in the 'EM' (Electronic Music, with capital letters, not to be confused with any electronica or any other electronic music that isn't made by fat middle aged blokes with more money than sense), but so few of them come even remotely close to capturing the band's brilliance. I came across a chap once who said he only listened to Berlin School music and literally nothing else. Life to the soundtrack of sequencers. Crikey.
