Well its a russian company, and took part in the solarwinds hack, that was directly funded by the fsb. So, yeah, it should ve scrutinized, nitpicked and avoided at all costs.
Its 2026, there is no need for a proprieraty IDE that is stuck in the early 2000s.
JetBrains is and has always been a Czech (and, thus, EU) company, not a Russian one. Yes, the founders are Russian, but that does not make the company so. They did have Russian offices, but closed them after the start of the Ukraine war [1].
The only confirmed link to the SolarWinds attack seems to be that SolarWinds was using TeamCity (JetBrains' CI/CD product) and that this was alledgedly used as a "gateway" to SolarWinds' systems - which doesn't require any cooperation from JetBrains, just an unpatched security issue. In fact, a patch by JetBrains for the exploited issue seems to have been available, but was not installed [2].
So while any company deserves scrutiny, these particular allegations against JetBrains smell like FUD to me.
The company was registered in Prague for political and financial reasons, but it has always been Russian to the core. Yes, they had multiple offices outside of Russia, but they were still mostly populated by relocated Russians. That's why their product quality significantly dropped since 2022, as they've cut themselves from their main source of engineers.
Still has room for improvements, like finally getting their own incremental compiler instead of reusing the one from Eclipse, and better defaults for type inference tooltips and inspections.
Only last year finally got to support JNI development with mixed language debugging, which Eclipse and Netbeans have supported for the last 20 years.
Its 2026, there is no need for a proprieraty IDE that is stuck in the early 2000s.
