Not OP but isn’t your definition of gatekeeping in all industries and it is wrong to point out industry expectations (of course delivery matters)? Like if a kid learns programming using Scratch, you’re not gonna be like NO! Real programmers use C++! But if at one point the kid wants to take programming serious enough, you should explain to them that the industry expect certain tools and skill set. I would argue CAD/CAM packages are the same. While there’s absolutely nothing wrong with fusion360 (I use it to for persona use too), it is true how the market penetration is extremely slim. Even the industrial sibling Inventor has only a small percentage of the market. While a lot of it is historical reasons, there are good reasons why most small to medium sized companies use Inventor/Solidworks and MasterCAM as their main driver.
