I thought universal calls to action phrases were not allowed, (ie "click here," "link here," "visit this link," "this site is,") regardless of content, especialy in the title.
Well one of my competitors has this as an Ad Title.
"Name Of Software": Download Now
Is this allowed, after all it's a call to action, and in the Ad Title as well.

Anyway, in regards to your question, I would not worry about witch-hunting your competitors ads. Instead, focus on making your own ad more targeted, and if it gets disapproved, only then refer to your competitors ad as a reference to why your ad should also be approved (if it is similar).
As long as what you say can be done.... can be done and free is fine as long as it is free, if it's free but you have register, then that needs to be explained.
Easy enough in 70 characters.
At one point the issue of having the keyword in the title made some keywords have 6 or 7 out of the top 10 have the same title, so if I am looking to select an advertiser and they all look the same...... relevancy isn't there, or unique relevancy that is.
