im glad you took this discussion to the FSDG mailing list - this is the appropriate venue to discuss such matters
you should not single-out parabola though, WRT the telegram clients - nearly every distro distributes telegram clients, including trisquel, guix, and pureos - the purpose of this work-group is to make decisions which affect all FSDG distros - if this work-group concludes that some program is unfit, parabola would remove it immediately, and the others should too before such a general consensus is reached, it is best to avoid asking any one distro to remove some software, which the others would still have, because the others were not included in the conversation also, there is no reason to single-out that one program - the very same argument could be made for many programs, such as 'hub' and 'weboob' - i think you could serve your own argument better by generalizing it, and removing focus from any one program or service
