I know. But still I would prefer something a non-profit or volunteer-driven project over one from a for-profit company. Especially in the adblocking business where investor concerns are very likely not going to be aligned with consumer interests. It's not about it being free, I support several free open source projects with donations. I just don't like the clashing interests.
For me that means Firefox, uBlock Origin and pihole (though I ran dnsmasq myself for a while, I like what they've made of pihole now, it's come a long way!)
I also don't like it as AdGuard is a commercial company, and I have zero need for the added features like parental control.
But I don't really care, I run all the dockers that have nothing to do with home assistant outside of hassio anyway.
