They gave the PC business away to establish the x86 standard and pave

PS/2 and that was very successful.

You are operating under the delusion that big old IBM, which should be a
dumb monopoly like AT&T if I follow you, somehow could see the whole
future of the computer industry in 1981 when they took a flyer on a
PC when no one at the time could even figure out why anyone needed one
or what they would do with it.

IBM was already talking about the "distributed
computing" model in the mid 70s

Yes and others were doing it too, particularly DEC.

and the PC was the perfect platform for it.

No it was not. It didn't have anything like the horsepower
then to do much of that. Useful for word processing and
spreadsheets etc but not for true distributed computing.

IBM still envisioned PCs being connected to mainframes

That's wrong too. Most PCs never were.
They were standalone computers.

and that is why their main thrust was at the business world.

It never was with the PC. That came later with
the PS/2 and still wasn't true with the stupid PCjr.

They gave away the x86 consumer business,

Bull**** they did.

just to establish the standard.

That didn't happen either. And while they tried to do that with
the PS/2, they failed dismally because the industry ignored it.

There is no better way to flood the market
than to give the technology away for free.

They never flooded the market. And they realised their
mistake with including the circuit diagrams and bios
code with the PC and XT and didn't do it with the AT

You also got PC DOS for free with your system.
(Not MS DOS, PC DOS, the one IBM owned)

51xx PCs were totally off the shelf parts and the 5150 PC-1
was shipped with full schematics and engineering documents.

And the bios code listing too.

The 3270 coax card and 5250 twinax cards were part of the original
PS/2 announcement, allowing them to immediately replace a dumb
terminal. They already had 3270 versions of the PC and PC/AT with
an identical keyboard so it was seamless for the operator.

And few bothered to buy them.

I am not sure about what happened in the upside down world south of
the equator but we sold the **** out of PCs being used as smart
terminals here in the US. In fact by the early 90s it was getting hard
to find dumb terminals in anything but the places with the simplest
applications with marginally trained workers. Places like offices,
insurance companies, hospitals and such, they had gotten rid of their
dumb terminals and put in PCs by the time I retired in 96.
They were even using PCs in Burger King and Wendy's for the cash
registers. BK used a regular PS/2 M/30 and Wendy's had them in a
custom cabinet but it was still a M/30 system board, unaltered in any
way.
