Sure, I found it there as well.

However, that is a far cry from your incorrect statement that "The limit of 51k EUR can be found almost everywhere [sic!] in their advertisements (flyers, online ...)".

It was certainly not in the flyer that accompanied their letter regarding the new "business package".

Not only that, the terms and conditions were not attached to the letter either; neither was a direct online link to them provided. I found them the same way you did, after doing some research and looking for them online.
