Why would Russia mark airstrikes with some kind of obfuscated Google Maps entries? I hope your hometown stays safe, but I can't see how this makes sense.
Any agent/soldier can access it without a complicated permission or authorization structure. You don't need access to some spy satellite. All you need is a mobile phone, tablet or laptop. It would seem very effective to me.
Not to mention the entire logistics side seem to have broken down entirely so coms and digital services being out / unavailable would be… unsurprising.
Its easy for local collaborators/spies to use this kind of system for communication with the Russian army.
No special skills or tools needed, and the on-line behavior is really hard to distinguish from 'expected' behavior. Its a pretty nice, and really easy to use, covert channel.
There is a saying in Russia, at war all measures and ways are good (на войне все средства хороши). Whatever can be used will be used either due to convenience, due to malice, or due to any other reason.
