The thing is they're still running the services whether someone in the UK consumes it or not.

I thought the primary reason for it not running commercial services was so that its integrity as an independent source of news and culture wasn't compromised. So surely by running anything commercial, it is potentially compromised.

You can already see that by the type of programmes that get made these days. It's clear much of it is made to sell to the rest of the world, rather than just for a UK audience.
