You could hold the balance long term and just disable autosavings so you don’t pay £1.50 / 28 days.
If Chip can offer a market leading rate and make this available to all savers, that should automatically prompt people to use the market leading rates.
MSE would say something like:

In an article, they might say:
Chip also offers the ability to autosave, though you pay a fee of £1.50 in every 28-day period you use that feature so if this is your main attraction we recommend looking at X and Y instead.
You also have to be able to link your current account, which means that you cannot use the account if you bank with a bank that does not have an Open Banking API.
Chip offers its rates by partnering with other providers and its rates are not fixed [unless they are] so be sure to keep an eye out for any changes in the advertised rate. You can of course close the account at any time should the rate drop.
Chip is a relatively new company and is currently rated 3.3/5 on Trustpilot.
