Disposal of 'old stuff' and data wiping

Replacing devices very few years is just not feasible even if it is small or uses replaceable modular designs. It is not easy to get rid of old tech (CRT tvs/monitors) although some electricity provides will haul away really old refrigerators.

It is also very easy forget that these will hold private things like passwords to various sites. Exactly how does one get into some of these devices to wipe that data especially with locked bootloaders?

You shred the device.

Profit is at least as important as saving electrical energy. Yes, operating a newer refrigerator does save a small amount of electrical energy, but in the US the recovery and re-sale of Freon is worth many hundreds of dollars per refrigerator.

Most larger food-handling businesses (restaurant, grocery, delicatessen, etc.) depend on a walk-in cooler, which is a refrigerator so big that you walk around inside it. The refrigeration unit of a walk-in cooler is expensive and the design lifetime is 50 years or more. Walk-in coolers made before 1991 run on Freon. (Before Freon they compressed ammonia or evaporated water. Ammonia leaks can kill people, evaporating water has its own problems.) Maintenance of the compressor/evaporator/etc. requires adding Freon because the capture and re-use of the existing Freon is not 100% effective, and because during normal operation a small amount of Freon escapes by diffusing slowly through the aluminum piping. Maintenance is expensive, but the cost is small compared to the cost of replacing the entire cooler; the old unit does not work with newer refrigerants. The payback time for replacing the cooler and using less electricity in a new unit is much too long for most businesses.

By international treaty Freon is no longer made, so the only way to obtain Freon is by scrapping an old unit which has some. The freon in a working consumer appliance (refrigerator, automobile air conditioner, etc.) made before 1991 is worth at least several hundred dollars. That is why the recovery operation can afford to advertise, offer an incentive to the consumer ($80 typical), send a truck and workers to remove the unit for no charge, etc.

In Europe, we have WEE - "Waste Electronic Equipment" (I think I've got it right).

In other words, if I buy something covered by the directive, then the retailer MUST take away the old item it is replacing, if I so ask.

It's WEEE: one extra E. Waste Electrical and Electronic Equipment.
