Poland already host OQ this year, they shouldn't host European qualification too. I would prefer Netherlands to host.
Ps; Turkey hasn't host major FIVB tournament yet. China/Japan host everything, Netherlands will host WCH'22. Not so much complain about this decision.
European qualification belongs to CEV, not FIVB. Turkey is going to host the ECH finals this year. Of course people can complain.
The hosting spot is only about money. It has nothing to do with what tournament they have hosted or they are going to host.
