Every company in the world is going to try and make sure they own as many TLD-variants of their name as possible.
I used to work for a small IT services which is also a small registrar (for .uk domains). One of our customers was in fact doing that - it was "interesting" keeping on top of all the renewals which for various reasons* had to be with several resellers. IIRC they were up to 40+ when I left.
* Mostly to do with various registries' requirements such as having a "business address" in the country - which was usually dealt with by a reseller having an "office" there that all their clients used the address of.
