It&#x27;s funny how so many development communities feel like they need to start over and create an entire new framework.<p>Perl 6, PHP 6 (which was never released), the disaster that is Python 2&#x2F;3 (many standard libraries were renamed breaking a ton of libraries, and now Angular.<p>PHP, which is hated by many here because it isn&#x27;t hip, at least allows you to run 4 code on the 5 interpreter with no issues.<p>When Microsoft did this with VB back in the 90s, which caused DLL hell, the community raged.  Now it&#x27;s a normal part of development.<p>I feel like it&#x27;s only about the money.  Many open source communities make money on support only and can charge companies lots of money to make the shift.  It also means tutorials, books, speaking engagements, etc.
