rust and maybe go, in a way evade what open and free code really meant (which contains the characteristic of being self contained). Many rust written software demand to the minute release of dependencies, automatically drawn and utilized while you compile the piece of software. First there is no way you can audit this then at any given moment this drawn code can change affecting what you compiled, exponentially making it difficult to audit and certify as secure. It also transfers the responsibility to 2nd and 3rd parties of what the code contains, making it legally impossible for being responsible or being accused of creating back-doors and other weaknesses in software.
But it is modern and it is being pushed everywhere. In general, when you hear buzz words and terms, and technologies, making noise and be utilized everywhere be ware of the trojan.
Facebook which had contributed 0 to the FOSS community, suddenly released zstd which they bought from someone (or so they say) and made him rich. This FOSS within months was incorporated and utilized all across the linux community on very false data supporting its superiority, like publishing comparative compression/decompression numbers of multi-thread software vs a mandated single thread on the competitor. At the end nobody really even used this optimized condition under which zstd has a tiny superiority in speed while still lacking in space (compression/decompression software).
Someone and something drives this "rush", like gold in Columbia river advertised by tool merchants for gold diggers.
At least on the left we should have a bit more critical tendency than anti-windows fan boys clubs. The price you pay to have a usb stick automounted rw as a user automatically upon insertion is one of security and privacy. All this overhead instead of 5lines of script.
What is so bad about allowing a large corporation to voluntarily draw data out of your system? For one it is very much against the fundamentals and principles unix and foss were based. One the earlier days selling point for FOSS was to assure the user there was no "telemetry". One the other extreme the public through android and mac/os have been conditioned to allow telemetry pretty much with every application they ever installed.
