Dear all
I confirm this view:
the way in which Wikipedia is working:
The power to edit is the foundation of all Wikimedia projects.
Any attempt to shut out some "undesired" users will also reduce the
inflow of competent, well-meaning users.
Wikipedia and Wikidata alike are built upon the bet that there are
more things to be gained than to be lost by being open.
Best regards,
Markus
