Anyway buying competitors has allowed Autodesk to shape the US AEC industry toward proprietary file formats such as Revit, while their low end product AutoCad Lite insures that small shops never automate and the construction design industry buys subscriptions in the hope that this year's features will actually effect the bottom line. They won't.
It's a great example of how to run a startup that creates a monopoly. They beat Adobe to the subscription model by more than a decade.
The Autodesk File is an excellent look inside its early days: https://www.fourmilab.ch/autofile/www/autofile.html
On the other hand PTC is a similarly sized company with a similar strategy of acquisition. It predates Autodesk's acquisition strategy and appears to target a different set of customers...hence no webstore. I suppose the analogy I'd draw is that AutoDesk has products that dominate their market segments in the way PhotoShop dominates its segment. There are competitors for profitable corner cases (in PTC's case product life-cycle management solutions), but those aren't in the just whip out a credit card and wait for the UPS truck sweet spot.
As an aside, my comment mentioned AEC and that's a market that Autodesk has clearly shaped and dominated.

And it's just swell.
It is fast and easy to use, would recommend if you're a Adobe Illustrator user looking to switch.

I guess Autodesk bought Indeeo?
I'm not sure exactly what you mean by 'freehand tool': do you mean something other than the pencil tool?
