It is just a word. A word that carries far more weight than it really should in our society.
I kinda like the idea of "privacy is sexy" which is how I read it.
The only possible issue is I can see some companies blocking it due to "Sex" but that's their issue with way too strong rules.
If it should or shouldn't carry the weight is irrelevant, "Sexy" does carry weight so surely the problem is obvious.
Besides, speaking from first hand experience, historically 'sexy' content on the internet usually came with a Malware/Virus, not a good association when the intention is to run scripts that make significant changes to your computer configuration, all for a novelty that lends nothing to the product.
With that being said, I have no issue with it personally.
1. Arousing or tending to arouse sexual desire or interest.
2. Highly appealing or interesting; attractive.
3. Having sexual appeal; suggestive of sex.
While #2 might be the intent, there are much better alternative choices for links that I could
* send to my 10 year old niece who is interested in tech
* share with co-workers or on company forums
* use without hassle from automated filtering/proxy/scanning tools for a TLD that is associated with adult content
