Is YouTube trying to block invidious?

WTF is going on now? I was using http://youtu.be to view videos on YouTube for some time now and now I'm seeing the following message.

Can't load the video on this Invidious instance. YouTube is currently trying to block Invidious instances. Click here for more info about the issue.

This is starting to worry me since I had been viewing YouTube videos via Invidious for privacy reasons such as I didn't want to be risking malware in the form of adware that could be linked to certain ads, and any ridiculously long ads if you know what I mean.

Right now, I'm just wanting what my options are now since I want to maintain my right to privacy and don't want to be getting exposed to risks.
