Swiss DAB hasn't flopped. "Because of the structure of four languages, in Switzerland, there are no national multiplexes. Four of the seven language regional multiplexes are run by the public broadcaster SRG SSR since 1999. The first commercial DAB+ multiplex was launched by SMC in October 2009 in the german part of the country, the second one (ROM) at the end of 2013 in the French speaking part. Since December 2020 SMC runs a second language regional multiplex in the italian speaking part of Switzerland (Ticino). SMC also runs four regional multiplexes since December 2012. The first local multiplex (Geneva region) started in May 2014 in particular for non-profit radios. Today 17 so-called “local DAB+ islands” are on air in bigger agglomerations of the whole country, all run by Digris."

It is only one regional language multiplex that is closing.
Not having a national multiplex has limited the profitability of the Italian language stations.
In reality this announcement just gives a "stay of Execution" until 2034 for FM analogue services.
As for any "bias", it isn't in the article that I see any.

This is old news anyway, the article is from April.
