Yandex huge privacy issue or not?

Their account system sucks hard. Had e-mail from long ago with phone number attached to it. Recently they decided to unlink it, because my accounts on Eats/Taxi, that used the same number and were initially registered with just phone number without providing e-mail are using it as separate account.

For the same reason wasn't able to migrate old Eats account, which existed on old phone (with unsupported Android version) for couple years but was impossible to login on new, because they introduced Ya ID instead and failed to convert old account into it. 3 weeks talking to support and they just make me spawn thousand more accounts but still without accessing old accounts data. Stopped using those since.
