I updated my original comment, and learned a good amount about that dispute as a result, so thanks for calling it out.
I think some people get touchy about them being lumped together if their last period of commonality (per the article) was 1400 BCE. For comparison, I believe all the Slavic languages were mutually intelligible around 1200 AD. But much more recently than this, in the last few centuries, there have been notable attempts by east slavs to absorb the Baltic language cultures and deny them.
I doubt West and East Slavic were. But inside those geographic groups they probably were (Czech and Polish AFAIR were around that time).
I was in Crimea for about 2 weeks (in 2012) they split me Russian there. I couldn't understand a word they said. And I didn't learn to understand than for 2 weeks of travel there.
I could understand some words from Ukrainian (I traveled by train from Lviv).
Another example is Croatian, I've been there on vacation and renting a room. I couldn't understand a word they said and didn't learn any.
TlI can understand some Czech (because this is the closest language together with Slovakian to Polish) but that's it.
I wouldn't mix Slavs from different groups together. They evolved separately and are as close as English and German.
It is an example I think of often, about how quickly languages can change. In the scale of 1000 years, a lot changes. Most of the diversity in Romance languages is from around that timescale too, it really started to diverge substantially around 900ad-1100ad.
I never said it wasn't.
Well, that and Romanian. And Hungarian. And outside the EU, Albanian. And Georgian, Azeri and Armenian if you consider those Eastern Europe.
Some of my fellow Romanians will also claim they're Central European, but in my mind, all the ones I listed are Eastern European countries. I'd even include Turkey and Kazakhstan in there, part of the latter is to the West of the Urals, which is what we normally consider the border between Europe and Asia.

Albania is clearly south east europe.
And, I don't care about your random Romanian friend's anecdote.
Yes, it is clearly south east Europe. East.
> And, I don't care about your random Romanian friend's anecdote.
Who's my friend?
In my mind, I was thinking of the belt of countries between Russia and Central Europe, starting from the Baltics down to the Balkan (excluding Greece).
There is a branch that contains both Baltic and Slavic languages, but there's also one that contains Albanian and Greek.
There have been some attempts to tie Albanian to Germanic, or Greek, or other branches, but they all have failed.
At some point they all are Indo_european, but they split a way ago.
and
> only Estonian is not a Slavic language.
So following this logic saying "in Eastern Europe, only Estonian is not a Baltic language" would make as much sense?
The fact they they are the closest surviving relatives on it own doesn't mean it makes sense to group them together (i.e. Italo-Celtic is also a theorized subgroup in a similar way but nobody is disputing that Celtic and Italic languages evolved into distinct groups).
Then there is a huge amount of missing links and unknown unknowns. e.g. Thracian and Dacian probably were also pretty close to Baltic or Slavic (maybe even closer to Baltic than Slavic is but we don't know enough about them to make any conclusive claims at all... but we at least know these languages existed)
