Europe is proposing to do away with key legal protections enjoyed by Google, Facebook and other internet giants, a shift that could lead web platforms to block certain posts by users.

New European Union rules, backed by European lawmakers in a vote Wednesday, could force web services to actively prevent copyrighted content from appearing on their platforms if rights holders don't grant them a license.

The legislation would also grant publishers new legal rights to seek compensation for snippets of articles that Alphabet Inc.'s Google and other news aggregators post online.
