Very few Blynk users are communicating with the server via MQTT.
To use your shoe shop analogy, how would you react if, as you realised that your customers were buying your $70 shoes and re-selling them for $500 ?
Blynk Legacy was built on a very different business model, with one-off purchases of functionality in the form of “energy” and the ability to install a local server if desired. Commercial customers were charged a much higher price, which effectively subsidised everyone else.
That proved unsustainable, because of the ability to share projects (similar to templates) and use a local server for business use.
The new version of Blynk has gone through a massive number of different cost model variations since it was launched, probaly in response to analysing how the various subscriptions were being used by various groups of users.
Unfortunately, Blynk has often made these changes without notifying users or explaining the rationale behind them.
It’s clear to me that too many users were using the Free plan, and I’ve always thought that it should have been a time-limited trial.
The Maker plan was a perfect balance for most people, with the possible exception of the multi-user restrictions, but clearly (to my mind at least) it was being abused by some.
You only need to look at some of the forum posts to see that people were using it for business orientated projects, and I would guess that the number of people who admitted to this were just the tip of the iceberg.
Sadly, the current free plan isn’t sufficiently powerful - in terms of organisational structure and user permissions - to allow potential business users to fully test the functionality. It’s also not very well flagged-up that there is a crippling monthly message limit, potentially luring students and makers into the product before they realise that their only option is to pay $99 per month or go elsewhere.
Given that situation, and the fact that the Pro subscription has a support desk ticketing system, this forum is effectively dead. Pro users don’t need to use it, and Free users who do are effectively time-wasters (even if they don’t yet realise it) because the product is crippled by the message limit.
