True the PI store has been defunct for years, and the raspberry PI foundation has gone back to the proven old ways of distributing software, of having an "install new software menu", which most Linux systems have.
No reason to mimic the tablet way of having a "software store".
underlaying the "software install menu" it all is the same apt-get system, just with a nice GUI shell.
The GUI shells also exist, but this one is just a bit more user friendly, but other Linux distro's have a very common one.
That the pi store is defunct (no more working) is no secret, but changing a blog post is not something we can or will do, we don't do "history falsification", so we don't change a blog, once it was posted.
This forum has a sticky and an announcement that make it blatantly clear that the "pi store is no more", and even explains why.
it was simply a failed experiment in software distribution.
we think the older way was better, and no one is trying to make any money out of it.
We often get complaints why this forum section isn't made "read only", but so-far we have resisted such temptations.
Oh, and the closure had nothing to do with "brexit", in fact it was closed long before anyone talked about that issue.
