Not true. I have a Canon Pixma MP170 and I regularly brought the
cartridges to a re-fill store and came home with one that was as good as
new. Some people even buy their own ink, at much lower costs, and refill
their cartridges.
Have another look.
Or, you can find a web page with details of overriding the cartridge status.

In some cases, there are even chip resetters, but what kind of dumb
design would allow resetting ? There is really no reason for a cartridge
like that, to be resettable.

I've heard of the chip counting printed pages, and the printer refuses
to print, even though the cart is half filled with ink. So the chip scheme
is a rip off.
Since all the money is made on cartridge sales, and none on the
printer, it makes sense for them to all be chipped. Any manufacturer
who leaves the door open to refilling, would need to charge more
for the printer, to cover losses on clever customers.

Information like this, can change at any time, as the needs of the business
change. The product that wasn't chipped yesterday, could be chipped today.

"Generally speaking, Canon, Dell, HP, and Lexmark cartridges are not difficult
to refill, though some Lexmark cartridges employ a built-in counter chip that
can't be reset; Epson cartridges also have a built-in counter chip, however it
is possible to purchase a chip resetter. As Brother cartridges generally lack
any chip and consist of merely a sack of ink, they can be readily refilled."
Read the Newegg or Amazon reviews for the printer, before buying. If the
chip prevents full cartridge usage, is non resettable or lacks an override,
then the reviewers (owners) will tell you.
Laser printers are suited to high volume printing, but I've heard of chipping
there as well. The per-page cost of a laser might be cheaper (at least for
monochrome printing).
