What justifies the huge subscription price increase?

So my Family Plan seems to have gone up 20% before tax, from $59.88 to $71.88, which seems a huge increase but it equates to only $1 a month.

I've just looked back at my invoices since 2018 and they all say $59.85, so this 20% is equivalent to 2% a year.

Everything seems to be going up, some things I choose to stop buying like coffee and beer which was £7 for a pint of ordinary bottled beer the other day with a meal when went out, an utter rip off.

$1 a month for something I use all day everyday seems quite reasonable to me :-)

I've edited to add that my Family Plan is used by 5 people so actually that is 20 cents each per month.
