In this case, if you can't buy phone insurance (the product you would buy from T-Mobile) from Lemonade, they are not competitors.
Does anyone know whether T-Mobile sell THEIR insurance or they act as brokers selling someone else's insurance (e.g. Allianz, AXA, etc.)?
I also wonder the % of revenue of T-Mobile from insurance Vs their other business lines.
(I don't really wonder)
T-Mobile does the same. So in that way they're no different than any other type of consumer insurance company.
So as I said, unless you sub-divide the insurance industry on arbitrary lines, they are both selling insurance to the consumer. Claiming that because it is only "extended warranties" (which it isn't anyway) isn't really a legal argument for trademark law. We're talking about markets here, they're both in the insurance market regardless of how you frame it.
I mean we are actually discussing “T-Mobile isn’t a mobile carrier, they’re an insurance company”.
You can't trademark the entire word "apple" you can trademark the the word apple within a set of industries. You can't start a computer/isp/copy machine company called apple, but you definitely can start a woodworking shop called apple.
Does it? Because that seems like nonsense.
Imagine if companies could reserve an entire letter. All words beginning with that letter would belong to them.

If you can trademark a name as simple as "apple", and if you can trademark an icon as simple as 4 squares of identical size and shape next to another (windows/microsoft), then it becomes quite obvious that colors are treated the same.
In the end, trademark laws as a whole will have to be reformed, but this is just a natural consequence of the current laws.
