Opinions are like ... well you know, everyone has one.
What follows is from what I have read rather than my own personal experience. Unfortunately I live too far from any active areas to keep up an affordable habituation program.
Habituation is a tried and tested method of interacting with animals of all types but each species has it's own unique approaches and cautionary tales.
From what I have read most people attempting to habituate our hairy friends have used primate habituation experiences (specifically chimps and great apes) as a basis upon which to build.
Is it possible? Why would it not be? Habituation isn't magic and is just making someone accustomed to some situation or thing. It applies to humans in many ways equally as relevant as it does to animals.
Most animals can be "habituated" to an extent but that extent varies on a number of factors of which some are controllable and some are not.
When I was a kid we "habituated" a family of Butcher Birds to take food from directly from out hands without much difficulty other than the right food, patience and consistency.
Regarding reverse habituation, my cat and dog habituate me every day at feeding time, pestering me incessantly until I give them what they want.
These are animals and Yowie/Bigfoot/Sasquatch have exhibited some of the same behaviours as other habituated animals, both wild and domestic. If they become overly reliant on humans as a source of food, to the point where it starts to change their foraging habits and they begin to cease foraging elsewhere as normal, then any sudden cut-off in the food supply can lead to problematic interactions.
This has been experienced with gorilla habituation groups and ended up with the gorillas being shot because they were encroaching into people's farm land and stealing food instead of foraging in their own habitat as they once did before they experienced habituation. Likewise our hairy friends have also at times become a nuisance in the same way.
So I think the key is to decide what you want out of the experience (define your end goal/s) and then:
1. Have an entrance and exit strategy. Build slowly and wean them off slowly when/if you are done.
2. Choose a suitable area and suitable food.
3. Find a suitable group. They have different personalities, curiosity and aggression levels so this will also affect chances of success.
4. Be consistent and punctual.
5. Watch for warning signs, unusual behaviour and be prepared to change your plan or cease all together if necessary.
6. Don't bring technology into the mix. It seems to be a deal breaker, so leave it alone initially.
No doubt people like Ray, Rusty, etc. who have experience at this will be able to better guide you.
