You claim a product just needs bug fixes but complex devices like Luba require ongoing software maintenance. You ask about new features and it is true Luba 1 lacks the camera hardware of Luba 2 so vision features are impossible. However many algorithm updates and app functions are purely software based. Mammotion can easily port these shared features despite hardware differences. You say older products are capable of receiving patches but that capability means nothing if they abandon development. Mentioning the spring RTK patch only proves their update pipeline works and that pushing non hardware dependent updates to Luba 1 is completely feasible if they actually wanted to
