Only if the "obvious reason" you meant there is "Google abusing its Android monopoly power".
I wish the EU would include that part into its anti-trust investigation against Google, too. It should be illegal for Google to ban ad-blockers on its store, for the same reason multiple courts in Europe have found that ad-blockers are legal: the user should have the power to block ads if he or she wants it.
This is especially true in this case, because Google can't even use the "security" argument as it did in the early days of ad-blocker banning. This app is functionally the same as a regular VPN, so unless it's saying that all VPNs are a security risk and it wants to ban all of them, then Google has no technical justification for banning VPN-like ad-blockers.
As as side note, why doesn't Blockada use HTTPS? My trust in that app dropped in half for this reason alone, when it's so easy and free to enable HTTPS these days.
On the subject of banning apps: my complete lack of empathy for less technically capable users is probably showing right now, but as long as I'm able to sideload apps onto my phone running AOSP, I'm good with whatever.
BTW was there any discussion on how Google could be split? Android doesn't bring enough money to develop it, it would make sense to just drop it. Manufacturers would need to maintain their own OSes, that might be interesting.
Firefox on Android supports uBlock Origin very well. It's awesome.
