Personally,I've never understood the issue of not wanting that very small link at the bottom of the page.
In certain business-areas, you do not want your competitors or users to see which software you are using.
Also very important:
When having the wording "Ltd." (Limited) in the footer of my website, my users will think that my website is not run respectfully or perfectly legal, because the term "Ltd." gives a very bad taste to some people.
Nowadays, many companies from foreign countries set-up a Ltd.-company in the U.K, because it only costs a couple hundred dollars to incorporate a Ltd.-company in the U.K.
If you understand how many hurdles and costs (minimum EUR 20K to 30K) are associated to incorporate a Limited-Liability-company in some other countries like Austria or Germany, then you will understand that a U.K.-Limited-company does not give much of a trust to users (thinking of users living in other countries than the U.K.).
So to summarize:
Just having the words "Ltd." or "Limited" in the footer of my website, this will give a very bad taste in the mouth of my visitors.
They will think: "this is just another small website-operator who wants to ripp me off and screw me".
Just because the liability of a U.K.-Ltd. is a few hundred dollars compared to a much higher liability $$$ in other countries.
The U.K.-Limited has not a very good reputation in some countries.
If you are aware of "laws of incorporation" in other countries, you will understand what I am saying.
I m actually perfectly fine to have the word "XenForo" and a link to the xenforo.com website in my footer, but the words "Ltd." and "Limited" I am not able to use as this will turn-off my users.
