Earlier quoted context omitted.
It's translating "alhamdulillah" to "Terrorist". "Alhamdulillah" is Arabic for "Praise be to god" and (edit: to my ear at least) is used by Muslims (edit: by Arabic speakers more often) nowadays as an alternative to Allah u Akbar, Takbir, or Narai-e-Takbir because (edit: I think) those 3 terms have increasingly been co-opted. This is the equivalent of translating "Praise Jesus" to "I love god and hate abortions"
> "Alhamdulillah" [...] is used by Muslims nowadays as an alternative to Allah u Akbar, Takbir, or Narai-e-Takbir because those 3 terms have been co-opted by Jihadists. This is not correct. Almost all of those phrases are commonly used in daily speech and prayers by Muslims globally. No group could possibly co-opt them. They are deeply rooted traditions.
Once a group that you don't want to be affiliated with starts to using it and the "outside" world associates the the symbol primarily with the "baddies", you rather look for another symbol
There definitely seems to be a trend of people abandoning Allahu Akbar
