I published using the Kindle store. It's not for everyone, but it scratched my itch. I framed my first cheque as a "published author" .. I didn't make any money, but that's not why I published.
You don't need anyone's approval, you don't need to pay anyone you don't want to and you can do it from anywhere with an internet connection.
I'm not sure what you are trying to tell us when you call yourself a visibly trans person. What you are inside your mind is rarely what is visible on the outside.
So, helping trans people, absolutely, but how about you, who is looking out for you?
Take it one step at a time. Practice makes perfect and it's likely that you'll fail many times before you succeed. Keep ar it. You can do this!
You can speak your mind and still be kind and considerate. You tend to catch more flies with honey and after a while nobody resents a hard truth in the mix.
On the other hand, being less considerate about truth means that people will ignore you or worse actively fight you just to spite you.
You definitely don't have to be passive, but you don't have to be a dick about your truth.
Note that I'm not saying that you're planning to be a dick, just that I've been where you are and don't wish that on anyone.
It appears that you think that I'm holding contradictory opinions. It's possible.
The "ICT aware" population is not what I'm concerned about and whilst that likely excludes both of us, it's the retired widow who needs a phone to track her diary and call an ambulance, it's the pig farmer who uses 123456789 as their email password and uses internet banking to pay his employees, it's the impatient mother of three who is running between venues to get her kids to drama, soccer and music lessons.
I have made house calls to these actual people and hundreds more who do not, will not, cannot, read warnings. They simply don't have the context to understand their severity. They don't understand why a camera has no requirement to read your address book or connect to the internet. They don't understand what a calculator needs to keep your screen on, or not. They "don't have anything to hide" and have no understanding how their address book and diary can be used to defraud them of their life savings.
I've spent a lifetime educating people like this. It's a drop in the ocean and all that happens is I'm pissing in the wind getting wet.
Is locking down Android helpful for you and I, perhaps not. But if I don't get a phonecall in the middle of the night because one of my clients just lost their life savings because their phone got "hacked", I'm a happy little vegimite.
Linux isn't ready for prime time because novice users have no chance to just do simple stuff like plug in a phone, download a video and tweak it, let alone open a spreadsheet or make a Christmas card and print it out.
You and I can do this, my partner cannot.
Another way to look at this is a 30 year academic with Mac and Windows experience who cannot figure out how to migrate to Linux.
I bookmarked it already and when I recover from COVID I'll add my two bits .. essentially, keep what you have, it's unique, it's memorable and already on every search engine.
I've been running Debian for over 25 years. I ran my primary desktop as a VMware virtual machine on a Mac since 2009, before that on bare metal. My late 2015 iMac died in June. I can no longer run my Debian desktop and bought a MacBook to use as a portable terminal it's not been a good experience.
I'm currently evaluating proxmox. It's not feature complete and I'm not yet prepared to build my future on it.
I might go back to bare metal for a while, but that's a big step backwards.
I don't think anyone is advocating turning off the side loading features, unless I missed something, but the complaints here appear that you have to do extra work to bypass security, which is not something I understand.
