So a lot of the things being discussed are meat and potatoes product management/development pitfalls. Scope creep/feature bloat. Not staying true to the market and users you are trying to address. Happens all the time.
Sparx is a reasonably priced sharpener designed to, with minimal upkeep, produce quality edges. Maybe not the equivalent of “artisan” sharpening as but most people can’t tell the difference anyway.
Adding features “just because you can” or because it is just an incremental (assumed) cost can lead to products that start to lose focus.
honestly, most players still don’t know much about profiling, and paying for the feature somebody might never use or use once a year might not make sense to a purchaser.
maybe it does, but product managers always are juggling features that will actually move the needle and that there is a business case for vs those features that some subset of the market is clamoring for.
