The sort of mapping we use are not important to a lot of users, as long as they can make out "safe depth" on their chartplotter they are happy. But for fishermen, especially in freshwater, Garmin is taking heavy hits to their sales already due to this policy. It will change in one direction or other, but it will not happen soon. Garmin has spent a lot of money over the last 7-8 years or so to get back in the top three of the marine industry. 4-5 years ago I would not even consider buying Garmin due to their crap sonar, it was worse then Raymarine, but today that is not the case.
Remember where Garmin comes from. Their core-business has way thougher standards for mapping then the marine industry, especially the part of the marine industry focusing on leisure-users. Getting the board of Garmin Inc to allow data into their products that they have litle quality-controll over is not something that will go down without a strugle. But I`m confident it will happen, or Garmin will revert back to saltwater cruisers as their main base of customers and all that money spent on R&D to develop/ buy tech used mainly in freshwater and/ or by fishermen will be a vaste. Vasting money is not good business, not even for Garmin.
