This is an extension of Ada Web with a widget engine backed by Highcharts JS library. Note that the Plotly-based widget engine, provided by default, has not been replaced, rather can be used alongside Highcharts wherever needed.
The default widget engine is set to Highcharts in the configuration as
widget_engine.defaultClassName = "HighchartsWidgetEngine"
If you wish to switch it to Plotly (as provided by a regular ada-web) add the following line to custom.conf
widget_engine.defaultClassName = "PlotlyWidgetEngine"
Furthermore, you can explicitly choose a widget engine (Plotly or Highcharts) for each data set independently by selecting Widget Engine Name under Settings -> General.

This restriction is enforced solely by Highcharts library (not Ada itself). Alternatively, if you do want to use this project for commercial activities you can do so by obtaining a valid license from Highcharts.
