I'm confused about the guidelines for asking questions about 3rd party software/plugins on this site.
On one hand we close questions where people ask for help about a 3rd party software/plugin (commercial and non-commercial). But on the other hand, it states in the What topics can I ask about here? article that
We also accept questions about community-owned, open source products based on the platform.
I have seen quite a few examples of questions about community-owned, open source products (i.e. non-commercial) that have been closed or put on-hold because they are (ta-daaa) questions about 3rd party software/plugins.
Is it a matter of opinion for the individual person (with enough privileges) to cast a closing vote on questions like these?
The reason I ask is because I've recently noticed people adding tags for 3rd party software/plugins that they are asking about and I have by default rejected any edits made to them because I'm of the understanding that unless the software/plugin comes from a Microsoft (SharePoint) official, they are best asked/answered elsewhere, e.g. the board/forum of the 3rd party project site.
How should I go about determining which questions/tags are allowed and which aren't?
