No, that was not exactly the reason. Have a look at Github, inform yourself on other sites. Then you will see how dead this project has become.
A simple example ?

Look at @XAVI, who is responsible for the documentation.
He was gone for two years. During this time nobody took care of it.

@Hatchat is all about control.
That's why the community was destroyed and limited to Japan, which looks more like incest to me. There was a photo in the forum back then that @Hatchet posted. A parrot, wrapped in some clothes, sitting on a shopping trolley outside a supermarket so it couldn't fly away.
This is exactly what happened with the XEM / XYM community.

There were enough resources available to initiate a sensible development spread across many countries. These were not utilised.

Is @gimre even a core dev anymore ?
All information, in all official sites, but also CMC, etc., about this project has long been lost. about this project is long out of date and only partially correct.
This is exactly the reason.
Look at the last upgrade of NEM, how badly it was implemented.

Why should someone starting with blockchain sign up with ‘X’ to get testnet coins to try out XEM/XYM ?
These should be freely available!
Why should someone register with "X" to take part in a dialogue?

@Hatchet:
"
We are also considering making Twitter account verification mandatory. We know that most members of the community have Twitter accounts, but we would like to hear your views on this.
"

What a load of bollocks and this woman knows it. I remember well in 2021 when she complained that hardly anyone from the community was on ‘X’.

Just as a simple reminder ... ‘permissionless blockchain’ ‘don't trust, verify’
