Why do YE's prefer to assume that decay rates (seemingly a basic property) vary with time when apparently there is evidence of other sources of neutrons which can generate 14C underground?

This is the most telling sentence in that page. It loudly proclaims the bias of researchers. In spite of the high degree of accuracy in 14C dating (Lacks precision though) they simply through it out because they don't want to see the evidence.
This isn't science this is story telling. We must explain it away, because if coal is less than 50,000 years old, than we are doomed. It isn't an anomoly it is an observation that nearly all fossil fuel (this is the first page I have seen that says that some fossil fuel is 14C dead, so I will look in to that further) contains 14C. This is as much proof that coal is very young as rediometric dates are proof of anything.
Again throw out this and there is no need to move further, because it will be plain that these dating techniques explain away what they don't want and claim loudly what they want.
1) Part of the problem is viewpoint. Just as you sitting in a red chair regard a stray blue fiber as coming from elsewhere, I might regard a stray red fiber in my blue chair as the oddity. It is clear that what different people see as problems depends on a lot on their worldviews or perspectives (young-earth vs old-earth).
2) What's wrong with assumptions ? [Almost everyone makes them.] The natural world is a very complex place and in dealing with difficult new problems with many parameters, it is often very helpful to make assumptions. The important thing is whether experiments justify the assumptions (at least in the cases studied). An assumption can be just viewed as a hypothesis which is accepted for the time being. The way science works is to come up with a model, test the model, reject or adjust the model in accordance with experiment. For example, consider Newtonian physics. It works fine as long as speeds do not approach the speed of light. [It seems to me perhaps that you are unhappy with the scientific mechanism ?]
Let's consider carbon 14 dating. Tell me what you think of the following:
a) fact: neutrons from cosmic rays can change 14N into 14C.
b) fact: living things exchange carbon with the environment.
c) assumption: the decay rate of 14C is constant.
d) assumption: the only 14C on the earth is generated in the upper atmosphere.
e) assumption: the 14C produced is in equilibrium with the rest of the carbon used by living things.
f) assumption: exchange of C essentially stops when an organism dies.
g) assumption: the percentage of 14C is constant over time.
h) more facts and assumptions
test:
i) carbon radiometric dating of historical objects works pretty well most of the time.
ii) carbon radiometric dating of trees (also dated by tree rings) displays slight discrepancies (a minor quibble).
OE response: (reject assumption g) the production of 14C is not constant or the worldwide carbon total changes (model adjustment - accept consistent tree rings and make calibration curve).
YE response: to be supplied by others.
iii) living mollusks can be radiodated to thousands of years old.
OE response: (reject assumption e) Some molluscs live in water in which the 14C is not in equilibrium. Support: measure 14C levels in sources available to molluscs, C mixing is much slower in water (especially layered) than in the turbulent atmosphere (or else we would all suffocate in our CO2 exhaust).
YE response: to be supplied by others.
iv) coal can be dated to various too recent dates.
OE response: (reject assumption d) Find another source of neutrons which can react with the 14N in coal to produce 14C. Support: measure levels of radioactive materials which produce neutrons, correlate amount with age, N content, etc.
YE response: (reject assumption c) Support ? to be supplied by others.
Conclusion: Scientific study of nature is an extremely complex undertaking. There usually aren't simple answers.
