If after ~30 years after break-up of USSR you have not gone back to russia (because quality of life in Estonia or Latvia is probably better), or have not learned the language or do not want to pledge loyalty to the country - then such person is a problem to itself. My social anecdotal bubble tells me that most of such people are very pro-soviet-union, but somehow idea of moving back to "mother russia" scares them.
Also in most post-soviet states russian communities can live all their lives without learning local language, i.e. there are native-russian kindergartens, schools, even university programs, russian entertainment and they can expect and be able to communicate almost everywhere in russian. So where's the bad treatment?
Putin's propaganda machine will make shit up on the spot - treatment of russian speaking communities is one of them. Maybe you also believe that there's fascist junta in Ukraine or Estonia? russian troll industry are masters of fake news - that will flood everything with multiple bullshit statements.
No, that is a statement that I consider false. I do personally live in a country that has a sizeable ethnic minority (Hungarians/Szekely, depending on the particular region of the country where they live [1]), and many of them do not know the local/national language, which is Romanian. Many of my fellow citizens regard that as almost blasphemy, I (and the law itself) actually have the contrary view, those people have the same right to Romanian citizenship as I do, even if they don't/can't speak the Romanian language.
While statelessness in the Baltic countries is a very controversial issue, I don't believe it'sas bad as people are making it out to be.
The absolute vast majority of those people don't care about the situation: they can work, they can travel through the EU and other countries, and they can play the victim card.
As a good example, Nils Ušakovs was the mayor of Riga, and his parents were stateless (and hi mother probably still is [1]). So its not like statelessness affects people other than the actual person (and the degree to which it affects them is very debatable).

"On February 25, 1994, Putin was also in attendance. One distinguished guest, then-President of Estonia Lennart Meri, gave a speech. Putin did something that has never happened at this ceremony: he got up and left. "With his legs straight [ed.: in a marching stance], throwing a contemptuous glance at the host, he left the hall, every step accompanied by the creaking of the parquet," according to a correspondent for the German magazine Zeit. "His exit was followed by whispers. Who is he? What's his problem?"
What exactly did Meri say that so annoyed Putin? The speech reads like a prophecy of what happened 20 years later in Crimea. And Putin's reaction shows that he sent a clear signal to the West.
The Estonian president referred to a paper from the foreign ministry in Moscow: "It notes that the problem of ethnic Russian groups in countries neighboring Russia cannot be solved by diplomatic means alone." Other means were conceivable for Moscow, Meri concluded. He warned against Russia's "neo-imperialist policy" and appealed to integrate Eastern European countries, including Ukraine, into the "democratic world."
Lennart Meri was a former filmmaker, literary translator, writer and IMO a world class intellectual with excellent speeches. For anyone interested, I google-translated this Hamburg 1994 speech to English [2]. The original source in Estonian is also present on the homepage of President's Office [3].
