This is malware behaviour and I don't think calling it that is an exaggeration.
I don't use any Adobe applications myself but somebody else on my home network does and I can tell you, Adobe app telemetry is very noisy.
Adobe telemetry domains like the following are amongst the top blocked by my local pi-hole installation which is using the OISD big list:
adobecorp.data.adobedc.net
aepxlg.adobe.com
hbrt.adobe.com
So this kind of behaviour is to be expected from Adobe but modifying the local hosts file is a new low, even for them.
my thoughts on software telemetry have remained unchanged since 2023 since I wrote this:
