Ukrainian here. Where did you hear that? Don't read news there anymore, they manipulate you. Ukraine introduced sanctions against russian businesses on its territory. As part of those sanctions, websites of three major russian IT companies have been blocked. That included Yandex (which is very similar to google, also has a lot of web services), and a couple of russian social networks.
I can say the same. Those services that were banned are either the most outrageous war propaganda outlets, or honeypots that gather intelligence information (imagine half of all Ukrainians communicating via a social network that is fully controlled by the enemy).
