I absolutely agree with this sentiment, and have erred towards buying family packs from Omni even when there was only one user in the house, simply because the tools have been useful to me, and I want them to be maintained and renewed.

I suspect that the new sensitivity of demand to price, however, is at least in part a result of the oversupply of mobile apps by developers with low overheads (compounded, no doubt by downward pressure on incomes). People have got used to paying sub-economic amounts, or even to finding free alternatives.

Not an easy environment to operate in, and not made easier by Apple's upgrade pricing inflexibilities.
