In a way, you are correct. But I think that the picture is WAY bigger. I started a thread about this issue, in early January, 2019, you find it here:
https://board.freeones.com/showthre...ASSWORDS-Massive-Mailadress-Password-etc-leak
There are links in my thread that offer an easy way to enter your variouzs email addresses, and see, if they come up in the bulk of data leak, along with the sites they are connected with.
Two of my mail addresses came up, and one of them specifically with my Freeones account. I instanly changed my login combination, just as I advise everybody should, even without checking, if it is leaked.
