Final answer:
Azure Machine Learning service supports a range of open-source technologies, including TensorFlow, PyTorch, and scikit-learn, contrary to the false claim in the question.
Step-by-step explanation:
The statement that Azure Machine Learning service does not support open-source technologies is false. Azure Machine Learning is a cloud-based platform from Microsoft that provides tools to build, train, and deploy machine learning models. It supports a range of open-source technologies, including popular machine learning frameworks like TensorFlow, PyTorch, and scikit-learn. It also integrates with other open-source tools such as Jupyter Notebooks and the Python programming language, which enhances the flexibility and accessibility for data scientists and developers.
