As a member of the tribe, I can tell you that no eyebrows were raised in the Jewish community that I was ever made aware of.
Honestly, the entire idea that "phylactery" is a synonym for "tefillin" is one that's near-totally gentile in nature. While there might be Jewish communities out there that use the term phylactery, it's exceptionally nonstandard for a Greek term to be used, rather than a Hebrew one.
From what I've looked up before, the only reason the word phylactery is associated with teffilin at all is because the ancient Jews essentially stole the idea from the Greeks in the first place. The way I heard it, they encountered Greeks who were wearing amulets with prayers to their gods (or just the gods' names, I'm not sure) on them, and thought "hey, that's pretty cool, we should do this" which eventually became boxes with small prayer verses in them. But the term wasn't brought over.
Or, at this guy puts it:
All of which is to say that the idea of removing the term "phylactery" in an attempt not to offend me and people who identify like me is at best pointless, and at worse patronizing. I haven't spoken to one other Jewish person who's approved of the change, and if there are any out there who think this is a good thing, I feel confident in stating that they're (extreme) outliers.
