What happened to the rendering of non-garmin maps on Garmin devices like Explore 2?

For couple of updates now, I`m observing that non-garmin maps are basically unusable due to the way they`ve started to be rendered by the Garmin devices (Explore 2 + Fenix 7) - the small roads (and others too) are so thick that it`s impossible to read the map.

Was that changed to lock users to Garmin maps? Is there any advantage of having such "update" for the user I`m not seeing here? Is there any way to solve the way those 3rd party maps are now displayed on the devices with latest FW versions?
