I don’t know the specifics behind why the communities were (re-)removed but the reasons given in the modlog seem vague enough to apply to anyone linking to Google or YouTube as they reference or indirectly link to piracy:

Removed Community CrackWatch@lemmy.dbzer0.com
reason: facilitating piracy, referencing websites used for the distribution of copyright infringing material in images

Removed Community Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ@lemmy.dbzer0.com
reason: facilitating piracy, indirectly linking to websites used for the distribution of copyright infringing material

From the initial removal announcement post:

The discussions that have happened in various threads on Lemmy make it very clear that removing the communites before we announced our intent to remove them is not the level of transparency the community expects, and that as stewards of this community we need to be extremely transparent before we do this again in the future as well as make sure that we get feedback around what the planned changes are, because lemmy.world is yours as much as it is ours.

EDITED multiple times due to confusion over origins of the ban.

      Yeah. They’re liars.

      Everyone should jump ship sooner rather than later.

      There are clear bad actors on the admin team. There is no hope for lemmy.world.

        There are no ships, it’s not reddit. You download one app to sync your instances, and you fucking join few to have access to everything you want. Or you just create your own instance, grant access to everything and use it by yourself. No lawyers will call you because they won’t even know. Lemmy instance admin can do whatever the hell they want, they could close Lemmy world tomorrow and I wouldn’t care, because there are hundreds instances in it’s place. Stop pretending that you matter to any of the instance owners.You are not a client here like on reddit, you are just a guest that costs them money.
