Overall Family plan issue:
I see people wanting different things for the Family Plan, some say there is too much storage (I personally do not agree with this), some say it needs more storage, others say it needs to allow for more users, while others want certain services and other don't want certain services.

It seems to me we are running up against the truth that 'there is no standard family', so the standard 6 member / 500 gb per member model doesn't fit the needs of many. We need a more flexible offering to attract more people over to Proton

I propose a slider style option, where people select the components that are important to their family and the price adjusts accordingly on the Family Plan.

Slider/Selectable options could include (Not all of these have to be implemented, they are just a starting list)

1. Number of members (3-10+)
   You could have 2-10 if you want to roll duo plan into family and remove the duo tier, simplifying offerings

2. Storage
   500gb - 1TB per user selectable.
   At present I think the family plan is poor storage value. You effectively get 500mb/user (6 users, 3TB in total).
   Duo gives you 2TB (1 TB per user) and Professional gives you 1TB per user, making Family plan look rather shabby when it comes to total storage compared.

3. Pricing overall
   Using $x times the number of users quickly gets too costly for most families.
   A sliding discounts model based on the more members you sign up the greater the discount might do well here. Retailers use this to increase bulk sales.
   I realise there is a base cost that must be covered with profit but when one compares the cost of say the Professional plan $7.99 on discount x's 6 users with double the storage those 6 users on Professional would get, it makes the family plan discount somewhat merger in terms of cost savings.
   I think more tweaking could be done here to bolster family plan value

4. Product inclusions
   This one is obviously tricky and could get messy in terms of product tracking but maybe having some of the products that are included be optional for a further reduction could be looked at.

I personally am ok with the products included in the family plan but if we are to consider tweaking of the family plan, then all options should be considered

Is it all too hard?:
For those that think this is all too hard in terms of product offerings, in a previous lifetime I used to work in some large Telco's and we had moved some of our service offerings to this sliding selectable model and it worked.

The hardest part wasn't the technical implementation it was convincing marketing and the business who want dedicated forecasts and defined projections to loosen up and try different things to remain competitive. Obviously you needs checks and balances in place, like limiting the plan changes per quarter or whatever your financial forecasting models are based on but that's easily doable.

Once you go down this path you start to see that this slider selection model can be applied to other plans also.
