obviously 'who' can change the verb and is not the same thing at all
I don't understand what you mean. You're not saying that a change of pronoun makes you change the verb into the infinitive?
Any others are not strictly British English - there are many here who speak and are influenced by American English, that does not make it official British English though.
It's used more often in AE, as the dictionary I quoted above indicates, but it is used in BE, too, and pretty often, I'd say. The quotes in #9 are from well-educated British people and from official government/university websites; could it be that you have simply never noticed that people use this form in BE sometimes, too?
Some more BE examples, this time with more detailed credentials:
"Many of the most gruesome crime thrillers are written by women - and lots of us love to read
them too" http://www.guardian.co.uk/books/2007/jan/31/c...
(written by Julie Bindel of the Guardian

"I’ll never make a novelist, although I love to read — Norman Mailer, Saul Bellow, Tom Wolfe, James Ellroy" - Sid Waddell, quoted in the Times http://www.timesonline.co.uk/tol/sport/articl...
- Sid Waddell (born August 10, 1940 in Alnwick, Northumberland) is a British born "Geordie" sports commentator and television personality. The son of a Northumberland miner, he attended King Edward VI School (KEVI), Morpeth, and he went on to obtain a scholarship to St John's College, Cambridge, where he graduated with a degree in modern history. He currently lives in Pudsey, Leeds. http://en.wikipedia.org/wiki/Sid_Waddell
These are just two examples, but it didn't take more than a moment to find them. Listen out the next time you have the radio/TV on and you'll hear British people saying "love/like to do X" all the time.
