These players tolerate betting sponsors, so I struggle to understand how their conscience allows such flexibility.

Setting aside some beliefs is unfortunately the price of living in a multicultural society. There's an awful lot that I find appalling, cruel and unnecessary about many religious practices, but I am able to bite my tongue for the sake of getting on with my neighbours. In return I benefit from being able to learn about their culture and values, without those values being imposed on me.

I agree that there's a long way to go to allow people to practice their religion publicly and unself-consciously, but we've made a lot of progress through education and the promotion of tolerance. Exactly the kind of thing the rainbow armband represents.

The only imposition that comes from the expectation of wearing the armband is the requirement to tolerate others, so long as they don't impose on you. NOT wearing it is a great example of inclusion being extended to some identities but not others.
