Well ....
Firstly Maru isn't totally Android ...since the moment you plug into a monitor you are in a containerized Debian 9 at that point..
So you are half right with Maru....
And you are completely right with Bliss..
concerning Android

I do think however ...that you may be at this moment a
"no-glass at all ...to be either half full or half empty...kinda guy"...
from how I am seeing this dialogue play out..

Since there is Sailfish...and others not mentioned by me...
Which aren't Android oriented as well...

If you desire to vent about the lack of OS's out there ...
vent about the lack of alternatives ..
and wish to vent about the domination of Android ...
I understand and sympathize...

But my sympathy doesn't go very far...
Since there ARE viable alternatives..
And quite a few too....nowadays...
This isn't 5 or 10 years ago..
a great deal has changed...
there are alternative OS's that are options, that aren't Android based..
There is still a ways to go...but that is always the case...
So I don't quite think it is as bleak as you paint it.

And now this is the time in the conversation where things are going to start changing...
Go back and look at the totality of my preceding post.
Then look at the edited clip of it you took and used for your purposes...
I think taking a clip ...of a statement... mentioning 2 OS's out of the others I also mention and calling them "a heap" ..is severe over exaggeration ...

Next...
this is the part of the conversation where I tear you a 2nd a*****e...
You don't have the right ..
Don't you f*** with my words and cherry pick them and try to use an edited version of what I said as your argument...
I'm not your stooge ...
Find another patsy for your angst..
I am not interested .
