I've snipped the rest of your post for clarity. I largely agree with what you're saying.

For leisure passengers, the changes to the BA Holidays offer is obviously the way BA believe they can get additional spend. Instead of booking flights and hotels separately, there's now an incentive to bundle your hotel in with your flights. Whether that incentive is strong enough to offset the competing incentive to credit to the hotel's own loyalty scheme will be for each person to decide for themselves. Certainly for me I have several city breaks in a year , usually flying economy and using the savings to pay for a better hotel, and the changes would incentivise me to credit to BA.

For business passengers its a bit more complicated but I do wonder if the increasing use of economy-only corporate travel policies has pushed some of the change.

The tiers should be aspirational but no so far out of reach that they feel unattainable. I have a sneaky suspicion they've overshot on some of the tier thresholds- even for business customers a £20K net spend is a big old chunk of money- and this is where any walking-back (should there be any) will take place.
