While adding usage guidance to a set of related tags on Stack Overflow, I found that the links in an existing tag wiki (twilio) included custom analytics. Example:

Apparently the vendor of the software that the tag covers had a marketing campaign in 2014 that targeted SO users. I think that this is at least Uncool, so I've stripped the URLs bare, while also removing the marketing voice from the wiki itself.
Have I over-reacted to this situation, or is it OK for such links to be embedded in the sites?
