Hi Ingmar,
Yes, it is free to redistribute those versions I released under opensource licences if anyone has such wish. So, anyone can write a blog post and attach those files for download.
But EllisLab should not force ME to distribute them either through EE forums or for free or both. I wrote those forum entries and I attached add-on files to them, so it’s ME who share them in this case. But I don’t want to continue this way. Now I uploaded the files of all my add-ons to devot-ee.com and I want it to be the only channel through which I distribute my add-ons.
EE forums were once a great venue to distribute and discuss add-ons, butt EllisLab suddenly reorganized forums without any prior notice to developers and without giving a time to adjust to the changes.
So it seems that I as the author can justifiedly ask forum moderators to delete the files I do not want to share through EE forums.
