It's not deceitful at all. Anyone who's in the WP ecosystem understands this.
Jetpack is part of Automattic. Automattic's main thing is wordpress.com (the hosted platform). Automattic and WP.org are not the same thing even though ( as with many open source projects that have commercial implications) the lines are somewhat blurred.
Presenting this as "deceitful" is really quite the over-reaction.
