>Does this have any connection with Apache Spark, or the Spark Java micro-framework?

Nope. Appears to be a closed source, set of php "RAD" components (auth, billing, subscriptions, invoices) that extends their relatively popular, but lower-level php web framework (laravel).

No connection beyond sharing a name. Can you elaborate on why you're upset about that?

Ambiguous names are an endless source of confusion and waste of time.

This is why context matters. Nobody in the Laravel community is going to associate "spark" with anything other than this project, and hardly anyone outside the Laravel community will associate "spark" with this project.

This is exactly the same thing that happens with https://www.drupal.org/project/spark.

Words mean different things to different people depending on context. Getting annoyed at that is really just a waste of time and energy.
