The association actually has every reason to thank Blocher. Without him, the association would not exist. It was founded with the sole aim of combating the former Federal saudi arabia rcs data Council's "local newspaper empire". as is freely admitted on the website. It states: "If a significant part of the media is dominated (sic!) by a single owner, this means (sic!) a reduction in media diversity."
The fact that the weekly newspapers in question already belonged to a single owner, Zehnder Verlag, apparently plays no role.
This example shows what the association specifically means by preserving media diversity: It sells a mailbox sticker with the inscription "Please no Winterthurer Zeitung". Presumably so that there is more space in the mailbox for the countless other local and regional independent media.
