@Meta-Chuh and all
The reason for @bruderstein to include some advertisement into his Plugin Manager was the high server traffic generated by solely the download of the plugin list - 70 GB per month as he stated somewhere.
His web hoster refused to continue that for free and GitHub wanted 80 Euro per month to host this file, which Dave was not willing to pay, additionally to all the work and time he invested in development of Plugin Manager.
So Dave asked his employer to host the plugin list file. They have been willing to do that but wanted their logo to be placed into Plugin Manager, which was the reason for Don to kick it out of the Notepad++ downloads.
Providing an all-time up-to-date plugin list for Plugins Admin will cause the same problem again. Let’s see how it will be solved…
Furthermore, AFAIK Notepad++ checks the SHA-256 hash value of the plugin list’s DLL file against a value hard coded into each Notepad++ release. This will not work anymore in case of continous updating that file. When I see the security issues that have been raised in the EUFOSSA bug bounty program for Notepad++, I suspect that a completely unprotected plugin list would also be considered a security issue.
