They definitely tried that with MSSQL. Didn't worked so far. But M$ tactic is always the same. Copy, throw money, copy some more, throw more money. If doesn't work, change the CEO, throw more money until the rival is dead. So yeah, they are throwing money to try to suppress PGSQL from existence. They did that tactic with Delphi (bought the main guy from Borland and that's how we got C#), MSSQL is their answer to PostgreSQL, ASP is their answer to PHP and so on. Oh, and if you think "MS loves Linux" is anything but this tactic, think again - WSL/WSL2 is the proof they still trying to kill Linux.
A terminal doesn't need SSH integration, but it's convenient if it does, to allow you to easily start and manage connections. Is there something inherently unsafe about such an integration?
What makes this one different though, besides being controlled by a non-Microsoft entity? Do they have some policies/mechanisms in place to prevent supply chain attacks?
The revenue tunnel vision disease that PMs have, totally ignoring features and other important things that have not a direct impact on that number. Hopefully we'll get a vaccine soon!
On a more serious note, security breaches can happen to anyone. Might not be fair to assume it's the PMs negligence. In fact, I met some that really saw the value in security and cared to dedicate the resources on it even if that meant not shipping more features.
The usual case for software development the last decade is developers who don't fully understand what they're doing, and are mostly focused on resume-driven-development (RDD) and looking good in Agile sprint standups.
Noteworthy exceptions: FAANG promotion bid orientation, and VC growth startup alignment towards shipping something to look like growth towards exit.
In a small minority of cases, you have developers who know what they are doing, and are thinking rigorously.
The norm isn't big-meanie Product making (forthright, courageous, photogenic) developers ship negligent security vulnerabilities, against developers' protests. Developers are at least as much responsible as Product.
