It would be so easy if adobe made it possible to delete fonts straight from the program instead of going to font book to uninstall. This is such a headache. There should be a way that the font can be selected and then click delete.
Don't you use the Creative Cloud app to activate/deactivate the Adobe fonts?
Generally, there are three categories of fonts:
1 and 2 are controlled by Font Book; 3 is controlled by the Creative Cloud app or the Adobe font website.
Note: some OS fonts cannot be uninstalled since they are required fonts.
Fonts are an integral part of the OS you are using, in this case OSX i presume since you mention Fontbook. The fonts activated via Fontbook can be used in each software that you desire. The option to remove fonts via Adobe software sounds rather ridiculous given that an OS would use the font as well. If you do not know how an OS works i strongly recommend taking a training.
And regarding the removal of fonts: why activate them in the first place?
Regarding your negative comment i strongly suggest not posting questions in a user forum for professional software. Your question was very negative from the start, almost blaming Adobe for not allowing a function which doesn't even exist in the OS which is Apple. So i am not really negative, just pointing you out on your lack of knowledge. If you think that is negative, then that is on you, i am merely holding a mirror. You should be checking your attitude first and then take a training to find out how an OS works and then take a guided tour for the Adobe software. You first have to crawl before your learn to walk.

We are mostly all users here and only a few can actually represent Abobe.
Deleting sounds problematic, but hiding should be possible, just like you can add a font to favourites I can imagine a filter to hide a font.
You can make a feature request here or vote here:
The OP was not confusing Font Book and Adobe, but asking for the ability to uninstall fonts for Adobe apps. Although this is an unlikely feature, there is no harm in asking. Ton pointed the OP to the correct place to ack for feature requests.
Not sure how having the ability to remove fonts from Adobe apps would work if Font Book is running too... but point taken.
Not certified (since, like, forever)
I don't think you will see this feature in Adobe products--however, I could see it available for Adobe subscription fonts sometime in the future.
In the mean time, get a second monitor if you don't already have one; open the Adobe software on one monitor and Font Book on the other (possibly the CC app too); if you see a font you don't want, move over to the other monitor and deal with it.
