Don't know about the linked site and its reputation. Found it myself quite clickbaity with the spying equipment twist. Here is more in-depth timeline kind of article from Estonia [1] and would recommend that instead.
I guess this is just local news in the world scale amidst current global events and you must find local source for any quality. Surely it has been covered a lot here in Finland nationally because of rather new kind of hybrid warfare escalation - response event.
