I wouldn’t use it.
Seems to me like free plan is what browsers natively support anyway. (Scam site blacklist. I highly suspect they use the same. They can’t compete with the one Google hosts and all major browsers integrate.)
And instead of paying 15 usd per month, Windows defender is a well funded, well established, well trusted solution.
There’s no practical gain in blockage before download. Windows defender scans upon and after download, before execution.
Insane.
Given the spread and damage of misinformation, maybe it’s time for state prosecution to not only pursue physical danger criminals, but also system society relevant destabliators.
