They build on onlyoffice for the office tools and use parts of nextcloud foe the desktop sync xlient but also add custom functions. I used it briefly and it looked nice, but I have my own nextcloud server with onlyoffice, so I had no need.

The industry is surely changing, but "the industry" is mostly geared towards enterprise, because it's where the money is. But the large amount of webpages are not enterprise pages but personal blogs, small businesses etc.
Many older projects don't get migrated to containerized infrastructure and smaller businesses don't want the overhead it creates to run a single app/webpage. Plain LAMP with FTP access is still the most common way to host I think (and thus the cheapest if you consider the amount of work that would need to be invested to containerize).
I'm sure there are a lot of reasons why PHP is better than Python for the backend, but I created an app wirh Symfony 5 and then an app with Django 4.
Symfony is so weird compared to Django. With Django I can just sit down and get things done. Symfony always seems to have some quirks which are mostly due to PHP (and me not knowing how to program in PHP).
That said, PHP hosting is so much easier and cheaper, this probably is important for smaller projects.
A report of 4 patients is hardly called a "study" and even less a "cure". Anti-viral drugs may have their application in long-covid cases, but usually the side-effects outweigh the benefits.

When the licence explicitly says all you are allowed to do is access the code "solely for the purposes of review, compilation and non-commercial distribution", that's not open source.
I'd say that is open source. But not free and open source
There's kind of a revival
