If you think a change of name would be better, then change it.
As for the criticisms, they seem to be based on misunderstanding.
> They say it’s better to dissolve this foundation or rename it because Free=

That makes no sense to me. I think this must be due to confusion.
A free software association is useful because it can raise money
and use it to do good things for free software and the community.
> Alao, they believe the name of it (Free Software and Open Source Associati=

> that it’s a representative of the whole community=2E
Why do they think it is “representative” at all? That seems like a strange
Does it _say_ that it aims to be representative?
If so, that explains why they think so — so change that statement.
