Honestly, looks like a cool designed website selling pirated content.
I guess no one is going to fill DCMAs for old eastern/russian movies?
Also with English subtitles.
You can find some Russian ones on YouTube, like the original “Solaris” — which I highly recommend. It is from the early 70s. No George Clooney or Steven Soderbergh.
Also, I'm not the biggest fan of copyright either.
What left me a bit sour about that website is not even that they are asking money but really just how they are pretending to be a legitimate business.
Instead, I'm more inclined to donate to people who make an effort to share rare and interesting content, for its own sake, like https://rarefilmm.com
"Decades old" is far from being sufficient to become unburdened by copyright. Works with joint authorship (as movies almost universally are) generally become public domain upon 70 years of death of its last remaining author - e.g. for movies you have to wait until the principal director, the author of the screenplay, the author of the dialogue and the composer of music all die, and then 70 years after that, so it's wouldn't be even surprising to have even the very oldest surviving movie of some country be still under copyright if one of them survived WW2.
Who would even own the copyright? The government? The director? Are they public domain? What's the continuity of the copyright?
They probably don't have enough commercial value to fight over.
Now if Ye used a sample of a soundtrack without authorization in a hit song, there's suddenly real money involved. Lawyers and artists would come out of the woodwork and start filing claims.
