Coffee addict is right. Their approach to halachah is agenda driven. At some point, when there is enough driving them (pardon the pun) towards chillul Shabbos, they will do that, just as conservative, which was supposedly halakhic, did.
True, other things may fall first, but it’s just a matter of time.
Hopefully, they’ll straighten themselves out and it won’t come to that, but that’s how it’s currently trending.
