I haven't seen the posts so I can only speculate.
The development team (and probably most of the community) prefers that updates to add-on modules be posted in the free downloads area, where some level of screening can take place to ensure that they comply with licensing requirements as well as making them easy to find.
Unofficial packages that mimic the official releases of the core code, in part or in full, will almost certainly be removed. Or links to them obfuscated if they're hosted off-site (which is worse).
The official releases are carefully tested before release to protect the community, whereas the quality of unofficial releases is unknown, especially where they are hosted off-site, a ruse sometimes undertaken by those wishing to insert malignant code (though I'm sure that wasn't your intention).
