They are mimicking Spotify. How they have music and podcasts built into one app.

what about apps that detect adblockers, will this bypass them or do they just not let you view their content?

The most I see is that they could see your IP address. Not good if you are being stalked. Again I don’t think this is a very big deal. If you are worried turn on a VPN.

What could a hacker even do with your Lemmy info? Unless you are posting critical information about yourself I don’t see this as a huge issue. More of a concern for the mod and admin teams imo
