Why is there no responsibility for that? And not just LaLiga, but everywhere?

You can claim copyright on anything anywhere, things get taken down, zero responsibility if it was wrongful, be it laliga streams, be it youtube copyright strikes or whatever?

If there was a law, that if you took down something that you shouldn't have taken down (eg. hundreds of pages), you should be liable for all the damages and income loss for those pages. Same for youtube... copyright strike, proven fair use.. now pay for the lost income of the creator, the creator (webmaster, ...) did nothing wrong, you should be liable for that.

In representative democracies, the laws (on everything, but especially so on property rights) are what they are because the people who benefit from them also, for the most part, own the politicians.
