That is correct. Many articles with comparison and product lists are under a permanent edit war of [interested] people adding and removing products.

This is more or less an argument that Wikipedia is impossible and shouldn't exist, since almost every topic is a potential battlefield. And yet the project not only manages to handle this, but counts among it's highest-quality FA contentious subjects like renewable energy, Everglades restoration, BAE Systems, and Microsoft's Security Essentials package.

In theory any topic could be a battlefield. In practise, there are only a few ones which have a lots of edit and counter edits.

Comparison_of_<something>_tools is one of them. The products will come and go, YYMV depending on when you read the list.
