Using app mamager and many other apps listed here requires root privileges. This means that you are able to modify almost everyrhing on the phone. From one side you are basically free to do what you want, on the other is true that becomes easier to escalate privileges. It is also true that if someone targets you and wants to hack your phone, he is gonma do that in any case because there are a lot of other security holes anyway. If you are using a GNU/Linux operating system, you have to deal daily with root privileges and this is not considered a problem. On phones its problematic to let users play with them because many of them will brick their phones like nothing so, it was chosen to limit the power that the user can have but this is an injudtice for who wants to do something more technical. In my opinion, the pros of having root privileges unlocked surpasses the cons. Especially if you mitigate the risks by doing regular backups and not putting all your life in your phone.

Yes, I’m gonna do that. It seems it lost the original format when I pasted it. (I wrote it before on LibreOffice Writer)

I modified it at the end. I remember that a long time ago (maybe 5-6 years) I found something about that but since now I cannot find it anymore its better to change it.

I have this one; https://www.404media.co/xz-backdoor-bullying-in-open-source-software-is-a-massive-security-vulnerability/

but I can rephrase it if you want

Be careful about few things: If you are living in the EU and ask to remove results about you, it will usually remove these results only for all EU versions of Google. This means that if someone has a VPN he can actually see them by connecting to a US server. The best strategy is to remove the original contents from sites also by contacting the owners. Then the results on Google will become outdated and most of them will disappear. In some cases like Facebook comments, they can remain in the search results even if they are already removed because they were cached by the search engine. In this case this tool should be used once the content is removed: https://support.google.com/webmasters/answer/7041154?hl=en

Remember also that other search engines like Bing may have results about you so, you should reach also their support pages if you really want to be forgotten.

I just make a something like a chingion tail. Normal pony tail + another half. This works for me.

So, I saw that lot of you are agreeing that basically just a standard CPU is needed. The problem is that in some cases its not enough. Some years ago I bought a very small Lenovo Miix 320 (not a thinkpad) and it was not compactible with free software at all. The audio and webcam crashed all the time with any distro that I tried. For this reason I asked this question, I had the impression that in the last years it became more difficult to make a laptop work with free software but I cannot judge it just with this experience.

So glad that I deleted my account from that site. All their books were possible to find elsewhere anyway.
