And how many airline passengers have Oyster cards?

Quite a few I would imagine, given the number of people living in
Greater London who have them and who might well be flying out of
Heathrow.

They don't need a free transfer, because their ticket will have been
valid to/from the appropriate terminal anyway[1]. So the travellers this
is aimed at will be landside transit ones, who typically aren't
Londoners [1](bis).

[1] Give or take edge cases like Londoners doing a transfer at Heathrow
without leaving the airport vicinity).

I take your point, but those of us who arrive or leave Heathrow by bus - eg
the X26 to Kingston/Sutton - that call (only) at the central bus station
will save a few bob when leaving from or arriving at T4 and T5. Bus often
beats rail for circumferential journeys from LHR.
