There is stuff like that going on in PCB design, where manufacturers make free design software, or distributors making footprint libraries.
Totally different things. Asking TMSC how to design a RISC-V chip is akin to asking Advanced Circuits or OSH Park how to design an Intel motherboard. They can make the board for you, but they dont design it.
TSMC is a manufacturer, but they still have a whole IP/Parts library that they share with their customers.
> TSMC's Design Service Alliance partners provide industry-leading, silicon-verified libraries, IP and design services directly to designers in fabless semiconductor companies, IDMs and systems houses. DSA partners provide best-of-class, silicon-verified libraries; high-performance, leading-edge intellectual property cores; unprecedented accuracy in design simulation, validation and verification; faster cycle time from specification through tapeout to finished wafers; and access to experienced designers and developers of complex functions.

There is eFabless, among other efforts in the vein you describe, they do a multi project wafer shuttle thing that google sponsors using skywater. It's supposedly an open source PDK, I haven't used it.
And that cost is exactly why it makes Zero sense the mainstream view on internet and HN that SiFive or RISC-V is going to crush ARM on Server / Desktop / Smartphone computing. Despite repeatedly asking what are the competitive advantage. Of course China betting everything on RISCV is a different story.
And this submission only have 52 upvote with very little comments. i.e It will never reach mainstream thoughts. Although I dont think any of the RISC-V Evangelism Strikeforce would want to hear them anyway.
