Ever since the big RIRs (like RIPE) have run out of IPv4 addresses to allocate - which was a couple years ago (ARIN was out 2015; and RIPE ran out end of last year - and that was already with quite restrictive allocation policies).
Even before the end of last year it was limited to exactly one last /22 per LIR for a few years already.
The pool that was set aside for that last allocation was depleted at the end of last year.
Now they are limited to handing out /24's that are returned to them to hand out to new ISPs (since going IPv6-only is still not quite possible..).
I know RIPE now want members to charge customers for IPs, but..
