The easy workaround, for now, short of paying for YT Premium, is to log out of your Google account, according to this:
Youtube’s Anti-adblock and uBlock Origin

So bottom line, if you can, just stay logged out of your Google account, or use a private window, and YT shouldn't block you due to your adblocker, for now anyway.YouTube isn’t rolling out the anti-adblock to everyone. It seems to depend on things like your account, browser, and IP address. And if you’re not logged in or you’re in a private window, you’re safe.
Okay, that explains why I'm not seeing it on my laptop, workstation or gaming PC. I do not leave those PCs logged into my Gmail/Youtube account in Firefox (well, I am on the workstation, but I only use Brave logged into Gmail to see my phone's texts, email, calendar and contacts, but I don't use Brave for anything else - it's just my Google accounts interface).
The Surface Pro tablet I use for reading my morning news, as I am now, is what stays logged into my Youtube account, because I watch YT videos on it that I subscribe to, and email myself links to the ones I want to download later for Media Center. It's the same account I use on my phone.
I just went ahead and paid for a premium subscription for that account, because it's worth it to me considering how many videos I watch on YT, and I have to be logged in to see my subscribed channels. I'm not going to play games with my UBlock Origin filters every month. As a byproduct, the Android YT app is now actually usuable on my phone. That was a horrible experience without premium - completely unusable.
