A company called Sporting ID have a central contract with the premier league for numbers and letters for which I imagine we will receive a fixed income. We have to then buy the numbers and letters from Sporting ID and if we sell over a threshold, we will receive commission.
We're allowed to make our own deal for the numbers and letters on the European numbers and fonts, but Sporting ID will probably have complained to the PL that people are not buying as much of their (standardised) numbers and letters from us if the bee mosaic option is available.
It is capitalism rather than anyone being bothered about what political message a bee represents.
