In my lifetime, all copyright changes have either been term extensions or measures that effectively strengthened copyright protections like the DMCA. So if I had to guess...
It's way worse than DMCA actually. With DMCA you can get takedown requests when one of your users uploads copyrighted works. Comply with the takedown requests in reasonable ways and you're fine.
The EU legislation means that platforms are liable beforehand.
Copyright law changes aren't good or bad; they serve certain people's interest and harm others'. Is it a good change or a bad change? That depends on what you want out of the law.
