If the only thing you are missing is youtube download ability, why not use one of the many options to do that from a handset? Newpipe or Spottube are on fdroid. https://invidious.io/ allows you to do it from a browser.
Your ISP can see torrent packets unless you are using a VPN. The other alternative is to setup a VPS and a torrent client on it. Then you download the completed files.
Notice that your if's are not part of this arrangement. You cannot opt out, and you do not get a cut of the opportunities created. The lawyers are Google ensure they get the benefit, and not us.
I agree that Nextcloud is a great solution. Some other cardDAV and calDAV solutions exist, but Nextcloud provides much more. Here is a little demo of Nextcloud on a handset. https://videos.trom.tf/videos/watch/5fc16e0e-f95f-45a2-9843-37749bf9dada
That is a greater good argument, but who really benefits here? In a somewhat best case scenario, some big companies and their equity owners gain all the data and perhaps develop proprietary solutions only they can prescribe. We then sacrifice our collective health privacy for some people who might benefit if they pay an uncompetitive price for the treatment. In a worse case situation, no cures or treatments are ever found, but these companies benefit from the surveillance and knowing what existing drugs and treatments they should invest money in to profit from, allowing them to game the market.
If this data was held in the commons and the benefits such as cures or treatments were not patented, we might have some incentive to provide it. In this case, everything is privatized for the benefit of a few.
They are collecting our medical records. I know this personally because an exgirlfriend of mine is a lawyer at Google and told me the same.
As others have stated, you are mixing search engines with metasearch engines here. If you employ browser isolation and obscure your IP address, you can be anonymous with any engine.
Yacy has potential, and I run an instance. It relies on us operators to index sites. You will find results to be incomplete in many areas, but it can be great for researching controversial topics. When I want uncensored and not manipulated results, I also use Yandex.com and Brave.
Fairphone should provide you sufficient privacy and security and give you ethical points. I have played with many OS's. GrapheneOS is hands down the best. I have used it for years. If only it would run on a fairly built device such as Fairphone, it would be stellar.
Yeah we all move on in life to other things. He provided a great information service to many of us. I am happy to see he is well.
I tried installing on graphene, but it got stuck in infinite loop for eternity asking me if I want to update. Perhaps this is a joke on the name? Good one.
I use moneybuster synchronized to my nextcloud, but it can synch to ihatemoney. Maybe it has more features than you want.
VLC is still my favorite all around player, and I would recommend supporting them with some funding to fix the bugs. You can try Auxio for local music and MPV for videos. There are many clients for streaming from your own server or others. It just depends on the protocol or platform you want to scrape.
