There are multiple overlapping products that both H&R Block and "Block" (fka Square) offer.
Up until now I did not know H&R as anything other then "those tax people".
Possibly I just did not notice, so when I got to the office I asked the 2 other people who were there, one of which is a bookkeeper if they knew what else H&R block did and all I got was "aren't they tax people"
So with my sample size of 3 most people just see H&R as tax people. However, they DO other things, how much I don't know but I can see them needing to / wanting to defend the trademark. OTOH, asking people what Square does you will probably get a longer list of stuff so H&R might have a bit of an uphill battle.
The other side of the coin is that as of NOW H&R Block has a market cap of $4 billion on revenue of $3.4 billion (as of the end of their last fiscal year)
Block / square has a market cap of $73 billion on revenue of $9.4 billion (as of the end of their last fiscal year) and as of now are on the way to having a $17 billion dollar year this year.
In theory Block / Square could absorb H&R somewhat easily. And add to their portfolio and services group.

Most of Block's revenues come from products that do not compete with H&R Block, such as credit card processing.
Cash App, which is owned by Square, purchased a tax preparation business from Credit Karma last year.
Also, just because a company has more revenue, it doesn't mean their reputation is necessarily better, or that they are shielded if they were to start using another company's trademark. For example, Ford's revenue is ~$127 billion, compared to Ferrari's EUR~3.4 billion, but even though both companies make good cars, with very few exceptions, Fords are not worth several hundred thousand dollars that Ferraris will often sell for. So if Ford were to start selling under the trade name Ferrari and were to sell what is basically a Mustang as a Ferrari, it would clearly be confusing to customers, and would be using the Ferrari brand that is not owned by Ford.
