Users say Adobe Creative Cloud rewrote hosts file to detect installed app

Oh helllll no. Let's imagine an analogy for Adobe leadership:

1. You hired a night janitor to clean and vacuum your executive offices.

2. That janitor secretly stops at every desk-phone to alter the settings of voicemail accounts.

3. After the change, any external caller can dial a certain sequence to get a message of "Yes, this office was serviced by Adobe Janitorial!"

What's your reaction when you discover it? Do you chuckle and say something like "boys will be boys"? No! You have a panic-call, Facilities revokes access, IT starts checking for other unauthorized surprises, HR looks into terminating contracts, and Legal advises whether you need to pursue data-breach notifications or lawsuits or criminal charges.

* Is it acceptable because they had some permission to touch objects in the rooms? No.

* Is it acceptable because the final effect is innocuous? No.

* Is it acceptable because the employment contract had some vague sentence about "enhancing office communication experiences"? No.

* Is it acceptable if they were just dumb instead of malicious? No.

No person that would blithely cross those lines can be trusted near your stuff, full-stop.

With the pressure from diffusion we will see more questionable business practices from Adobe and they weren't a saint before.

Agree with everything you’re saying but “enhancing office communication experiences” is absolutely the path they would take to excuse installing ads

All of the pirated Adobe installs require host file changes to redirect the license calls to local or nonexistent IPs. Maybe by Adobe adding this, it enables them to track pirated installs, since presumably the new host entry would reestablish the creative cloud connection...

Would be interesting to hear if any previously working cracked installs were broken...

From friends I know who tried pirated Adobe software, yes they confirm it.
