You are ignoring the real problem the user ktktkt is facing.
The real issue isn't that VBScript is "old"; it's Microsoft's decision to completely eliminate the language (even removing the ability to install it as an optional feature). This is throwing away the effort and investment of people who have relied on this language to develop systems for over 20 years.
VBScript is Not Equivalent to PowerShell
To say "the solution is PowerShell" is to misunderstand the use cases for these technologies.
VBA: Microsoft itself has been using VBA (Visual Basic for Applications) in Excel since 1993. VBA's basic syntax is nearly identical to VBScript, and it is used by millions of users to write macros. You don't just decommission a functional language with a million-user ecosystem after 30+ years by saying, "Oops, this is actually insecure." You patch it.
Classic ASP: Announced in 1996, Classic ASP, which formed the foundation of the internet at the time, was predominantly based on VBScript. You cannot expect a user to compensate for their accumulated knowledge in these areas (web applications, intranet portals, Excel automation) by simply telling them to "learn PowerShell."
Even if it were technically possible, you are ignoring the cost required for a company to rewrite an intranet application or automation system—developed over 3-5 years of effort—from scratch, just because the platform owner decided so. This means the loss of thousands of engineering hours and money.
This isn't the first time Microsoft has abandoned its users. They ignored Classic ASP users in the same way in the early 2000s. What was the result? At that time, while most of the internet was using Classic ASP, developers quickly migrated to PHP. For 25 years, approximately 80% of the internet runs on PHP. In fact, PHP's success paved the way for Python, which was born in 1991, to revive on the server side after 2000 and achieve its current popularity.
Microsoft abandoned an ecosystem it created (Classic ASP) and gifted 80% of the market to its competitor (PHP). Now, it is repeating a similar mistake by completely removing VBScript.
If Microsoft had made VBScript open-source and allowed the community to maintain it, this "modernization" move would be understandable. However, in its current form, this is a blow to the developers who trusted the platform.
Comments from users like ktktkt may be harsh, but this shows just how justified their anger is and how deep their disappointment runs.
