Yeah, I think calling the Mv3 versions "secure adblockers" would be more accurate.

How about "nerfed adblockers"? Do any of the MV3 versions replicate the full power of ublock origin on Firefox? (https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-b...)

To keep with the current parlance, "safe adblocker" would seem to fit better. Safe for whom, I think we all already know.

Secure for whom?

Browser users. Pre Mv3 extensions were a huge vector for malware. My in-laws were hit by that.

You can write malicious MV3 extensions. The changes' stated reason was performance, not security.
