1. An undertaking providing core platform services shall not segment, divide, subdivide, fragment or split those services through contractual, commercial, technical or any other means in order to circumvent the quantitative thresholds laid down in Article 3(2). No such practice of an undertaking shall prevent the Commission from designating it as a gatekeeper pursuant to Article 3(4).

2. The Commission may, when it suspects that an undertaking providing core platform services is engaged in a practice laid down in paragraph 1, require from that undertaking any information that it deems necessary to determine whether that undertaking has engaged in such a practice.

3. The gatekeeper shall ensure that the obligations of Articles 5, 6 and 7 are fully and effectively complied with.

4. The gatekeeper shall not engage in any behaviour that undermines effective compliance with the obligations of Articles 5, 6 and 7 regardless of whether that behaviour is of a contractual, commercial or technical nature, or of any other nature, or consists in the use of behavioural techniques or interface design.
