The only thing I don't like about subscription is rent-seeking. I'm fine paying a small amount every month if I expect security updates or small features that won't impede my workflow. If there is a lot of request for additional features, you can always bump up to a new version. If there aren't, that means your product is mature, or you may need to market to a different segment. But I'm not paying you every month just to shuffle the UI around or to be able to access my data.

You don't get to decide what is "small features" and if you start fragmenting software into multiple releases you are going to make it more expensive for everyone, because now the company is supposed to maintain N versions because you are a special snowflake.

Or you can sidestep the whole thing entirely and use/fund/ promote Free Software. Your "small monthly amount" will go a long way and you will be free to pick and choose as you want.
