I wonder if companies will be more careful with the possibilities of un authorized modding, there are economic forces pushing them to develop a high capability product, then dumb it down and release several lesser devices and call it a product family.
Absolutely nothing wrong with creating product families in that fashion. Products are not (should not) be priced according to what the cost of the actual hardware is, but rather on what the product is inherently worth and its functionality.
All FLIR has done is create a base product and offered several different pricing tiers with different sets of functions offered for each price tier. And again whether functions are implemented via software or hardware, it is irrelevant.
Look at software companies. They create a base product (i.e. Windows OS, Photoshop, Premiere, AutoCAD, or what have you), and then they do the same thing - they offer different versions of their products at different price points with different subsets of functionality.
Auto makers do the same. They create a base model, and then with some simple upgrades, they also create several different models based on one base model.
I'm willing to bet the market share of amateurs who buy these FLIRs and then will hack them is probably well less than 1% of all total buyers as almost all their products are purchased by professionals in the field who aren't really going to fret about dropping $5k for a piece of test equipment.

Can't you just take the IR filter out of any old crap camera that has a CCD and use that?
No. CCDs have no sensitivity in the LWIR range
LWIR photons do not have the energy to knock electrons out of the pixel wells, but increased temperature will cause increased leakage current and deplete the wells that way. This mean that image sensors have a low but quite measurable sensitivity, an exposure time of seconds to minutes is required.
Normal lenses are completely opaque to LWIR, and so are the filters mounted on the sensor. Instead of a lens you could use a curved mirror to focus the image but you still have to heavily modify the sensor.
What finally makes the idea almost completely useless is that the pixels are not thermally insulated from each other so heat will spread from pixel to pixel and make the picture just a big blur with a resolution of something like 8x8 pixels if you are lucky and have a very large sensor.
